ABSTRACT
Primary adrenal angiosarcoma is a very rare malignancy. This is a case report of a 54-year-old female, who presented with right-sided abdominal pain. Magnetic resonance imaging of the abdomen and pelvis showed a right adrenal mass with a maximum dimension of 5.7 cm. The patient went for a laparoscopic right adrenalectomy. The postoperative period was uneventful, and she was discharged on postoperative day 2. The patient was free from complaints at outpatient follow-up visits. Pathology confirmed the diagnosis of adrenal angiosarcoma and the metastasis workup was negative. A multidisciplinary approach through the expertise of medical oncology, surgical oncology, and histopathology is essential for the diagnosis and management of such rare diseases.

ABSTRACT
KEY CLINICAL MESSAGE: Angiosarcoma is a rare malignant disease with an extremely poor prognosis, showing rapid progression of the local tumor and/or distant metastases. Although multidisciplinary approach including systemic chemotherapy and radiation therapy is ideal for this disease, surgical resection have a role in disease control and should be performed as soon as possible.
ABSTRACT: Angiosarcomas originating from the tongue are rare and have extremely malignant features, leading to a poor prognosis. Herein, we report the case of a patient with angiosarcoma arising from the tongue who was successfully treated surgically. A 71-year-old man was diagnosed with a mass on the right side of his tongue and visited the Department of Oral and Maxillofacial Surgery at our hospital. The patient was referred to our department for further examination and treatment after a biopsy of the right edge of the tongue. An irregularly raised tumor 50 mm in length was noted on the right lingual border. The preoperative diagnosis was a primary angiosarcoma of the tongue (clinical stage, T3N2bM0, Stage IV). As his tumor had been growing rapidly, he emergently underwent partial right-sided tongue resection and right neck dissection without reconstructive surgery. The histopathological diagnosis was pT3N0. Postoperatively, the patient showed no signs of recurrence or metastasis during the 1-year follow-up. As for angiosarcomas, surgical resection is the only curative treatment, and surgery should be performed as soon as possible after the final diagnosis.

ABSTRACT
INTRODUCTION: Vulvar cancer is a rare cause of malignancy among women. It is key for surgeons to achieve negative resection margins, as it greatly impacts patient's prognosis. Unfortunately, additional surgical procedures are often performed due to the regional anatomical complexity. Based on non-palpable breast tumors, where image-guided preoperative localization tools have enhanced the complete resection rates, we aimed at evaluating the feasibility of magnetic seed technique for localizing perineal lesions.
PRESENTATION OF THE CASE: We present the case of a 40-year-old female patient, who underwent iterative resections for a recurrent epithelioid angiosarcoma of the left labia major. Imaging revealed a suspicious regional involvement at 3 months of follow-up, for which another surgery was planned. We decided to target this non-palpable lesion with the Magnetic Seed technique to guide the intervention. A seed was inserted into the nodule under ultrasound guidance. Resection was then performed, with negative margins and no recurrence on last follow-up.
DISCUSSION: Surgical procedures with minimal extension are recommended in vulvar cancer, to limit the aesthetic and functional complication. Unfortunately, recurrences and residual tumors remain frequent, even higher when surgical margin safety is not achieved. Many studies have suggested the benefit of image-guided localization tools in non-palpable breast tumors. By reducing the excising volume and focusing on the lesions, relapse and complications are rarer. We considered Magnetic Seed to be the most appropriated technique for perineal lesions.
CONCLUSION: As for breast cancer, Magnetic Seed technique could be appropriate for non-palpable perineal lesions, optimizing resection margins with minimal procedures.

ABSTRACT
INTRODUCTION: Angiosarcomas in the head and neck region are aggressive tumours associated with high local recurrence and metastatic rates. We present our 17-year experience at the North of England Bone and Soft Tissue Tumour Service.
METHODS: A retrospective review of our prospectively maintained database was undertaken, looking for patients diagnosed with angiosarcomas affecting the head and neck. Data were gathered using a pre-defined proforma to include demographics, histological characteristics, treatment modalities, adjuvant therapies, local recurrence, distant spread, and disease-specific survival.
RESULTS: A total of 23 patients (17 males, 6 females) were identified, with a mean age of 76 years at presentation. Fourteen presented with scalp lesions, whereas the remainder arose on the face. Eighteen patients underwent resection with curative intent, whereas three received palliative radiotherapy and two received comfort-based care only. Of the patients undergoing surgery, 12 had local flap reconstruction and 6 underwent free tissue transfer. Clear resection margins were obtained in nine cases (50%). Fourteen patients (78%) presented with local recurrence after surgery, and 11 (61%) developed distant metastases. The median disease-specific survival time for patients treated with curative intent was 38 months. Eight patients had mapping biopsies ahead of their resection; however, complete resection was achieved in only two cases.
DISCUSSION: Angiosarcomas of the head and neck are associated with a poor prognosis, with most patients rapidly developing local recurrence, resulting in adverse clinical outcomes. Mapping biopsies do not demonstrate a clear advantage for achieving complete surgical resection. A radical surgical approach is warranted, given the aggressiveness of the pathology. However, there remains no consensus on optimal surgical management; we recommend further synthesising studies to determine the most appropriate treatment pathway.

ABSTRACT
BACKGROUND: Angiosarcoma, a rare endothelial-origin tumor, can develop throughout the body, with the head and neck skin being the most commonly affected areas. It can also originate in other sites such as the breast, iliac artery, and visceral organs including the liver, spleen, and kidneys. Angiosarcoma of the bone is remarkably rare, presenting as either unifocal or multifocal bone lesions and often leading to a grim prognosis. Diagnosing bone angiosarcoma poses a significant challenge. 18F-FDG PET/CT serves as a reliable and indispensable imaging modality for evaluating distant metastases and clinically staging angiosarcomas.
CASE REPORT: A 57-year-old woman presented with a 10-day history of dizziness and headaches. Cranial CT scan revealed bone destruction of the parietal bone, accompanied by soft tissue lesions, protruding into the epidural space. MRI examination demonstrated lesions with slightly elevated signal intensity on T2FLAIR, showing moderate enhancement. Furthermore, multiple foci were observed within the T12, L1-5, and S1-2 vertebrae, as well as in the bilateral iliac bones. For staging, 18F-FDG PET/CT was performed. The MIP PET showed multifocal FDG-avid lesions in the sternum, bilateral clavicles, bilateral scapulae, multiple ribs, and pelvic bones. Heterogeneous FDG uptake was observed in multiple bone lesions, including intracranial (SUVmax = 11.3), right transverse process of the T10 vertebra (SUVmax = 5.8), ilium (SUVmax = 3.3), and pubis (SUVmax = 4.7). The patient underwent surgical resection of the cranial lesion. The pathological diagnosis was made with a highly differentiated angiosarcoma.
CONCLUSION: Angiosarcoma of bone on FDG PET/CT scans is characterized by abnormal FDG uptake along with osteolytic destruction. This case highlights that angiosarcoma of bone can manifest as multicentric FDG uptake, resembling the pattern seen in multiple myeloma. FDG PET/CT can be a useful tool for staging this rare malignant tumor, offering the potential to guide biopsy procedures toward the most metabolically active site. And it should be considered in the differential diagnosis of multiple osteolytic lesions, including metastatic carcinoma, multiple myeloma, and lymphoma of bone.

ABSTRACT
Squamous cell carcinoma (SCC) is the most common malignancy of the head and neck region. Most cases present little diagnostic difficulty on fine needle aspiration (FNA), but unusual variants can be problematic. The authors report a case of the acantholytic SCC of the oral cavity in a 36-year-old male. The FNA showed hypercellularity, with malignant cells arranged in isolation, loosely cohesive groups and a linear configuration. Such cells were round to elongated, with vesicular nuclei and prominent nucleoli. Cells possessed occasional intracytoplasmic vacuoles, misinterpreted on FNA to be vasoformative features as seen in malignant endothelial cells. The cytologic diagnosis was "positive for malignancy, suggestive of angiosarcoma". A total excision was performed and by histology, the tumor was diagnosed as acantholytic SCC. The malignant cells were positive by immunostaining for AE1/AE3, p40, p63 and vimentin, but negative for CD31, CD34 and ERG. The intracytoplasmic vacuoles were PAS- and mucin-negative and negative for the above antibodies. Testing for HPV (molecular and p16 immunostaining) was negative. This case highlights the diagnostic challenges on cytology when malignant acantholytic squamous cells show intracytoplasmic vacuoles, and stresses how immunohistochemistry is important for distinguishing acantholytic SCC from other mimics.

ABSTRACT
OBJECTIVE: Canine splenic hemangiosarcomas (HSA) are malignant mesenchymal tumors with a high tendency for metastasis. Median survival times after splenectomy followed by adjuvant chemotherapy usually range between 5 and 8 months. The aim of this prospective randomized double-blinded study was to examine the efficacy of a commercially available dendritic cell therapy (PetBioCell) following splenectomy. In addition, possible side effects of this therapy were evaluated.
MATERIAL AND METHODS: Twenty-one dogs with histologically confirmed splenic HSA without metastasis (stages I or II) were included in the study. Ten dogs received the dendritic cell therapy, and 11 dogs received a placebo. Injections were administered according to the manufacturer's instructions monthly for the first 3 months and then every 3 months until death. Survival times and toxicoses of both groups were compared.
RESULTS: Follow-up data were available for all 21 patients; the observation period ranging until euthanasia or metastasis-related death. One patient that had received the dendritic cell therapy was euthanized due to prostatitis and experienced the longest survival time (668 days). One dog in the placebo-group lived for 448 days after splenectomy. The median survival times in the dendritic cell therapy and the placebo group amounted to 74 and 126 days, respectively. There was no significant difference in tumor-free interval (t(18) = 1.4, p = 0.911) and survival times (t(19) = -0.094, p = 0.463) between the 2 groups. Toxicoses reported in both groups were mild and self-limiting.
CONCLUSION: Immunotherapy using autologous, immature and unprimed dendritic cells according to the PetBioCell method failed to show efficacy on tumor-free interval and survival time in the presented dog population with splenic hemangiosarcoma.

ABSTRACT
Cardiac angiosarcoma is a malignant tumor derived from vascular endothelium with a dismal prognosis. The imaging findings of cardiac angiosarcoma are nonspecific and endomyocardial and pericardial biopsies have insufficient accuracy. For these reasons, the diagnosis is sometimes difficult. Primary and metastatic tumors tend to bleed easily, causing hemoptysis and neurological symptoms. Brain metastases are not often known to be fatal when they cause hemorrhage. We report a 27-year-old man diagnosed with right atrium angiosarcoma, with metastases in the lung, brain, and bone. The patient had only respiratory symptoms at the first visit and did not show any symptoms derived from brain metastases yet died after 27 days due to hemorrhage from brain metastases. If brain metastasis from angiosarcoma is suspected based on imaging findings, urgent radiotherapy should be considered before histological examination for a definitive diagnosis.

ABSTRACT
BACKGROUND: Paranasal sinus angiosarcoma is an uncommon malignancy, with only a few reported cases worldwide. Although it exhibits multiple symptoms, facial paralysis has not been previously documented as a noticeable presentation.
CASE PRESENTATION: In this case, we report a 40-year-old male who presented with facial numbness and pain for one month, weakness of his facial muscles for 15 days, and recurrent right epistaxis for 1 year. He had a history of nasal inflammatory polyps with chronic sinusitis. Computed tomography and magnetic resonance imaging showed space-occupying lesions in the right nasal cavity and maxillary sinus, with bone destruction occurring in the sinus wall and turbinate. This patient then underwent endoscopic surgery. According to the histopathological and immunohistochemical results, he was eventually diagnosed with paranasal sinus angiosarcoma in April 2021. To date, this patient has not initiated any radiotherapy or chemotherapy and has survived with lymphatic metastasis for at least 3 years.
CONCLUSIONS: This manuscript suggests that paranasal sinus angiosarcoma can present with facial paralysis. Moreover, pathological and immunohistochemical tests are still vital for diagnosing paranasal sinus angiosarcoma and differential diagnosis. Additionally, regular follow-up is crucial for patients with paranasal sinus angiosarcoma, enabling monitoring of recurrence, metastasis, and recovery while contributing valuable clinical data to understanding this rare disease and associated research endeavours.

ABSTRACT
INTRODUCTION: Chemoradiotherapy with taxanes is well-recognized as a first-line therapy for cutaneous angiosarcoma (CAS), but second-line therapy for CAS is still controversial.
CASE PRESENTATION: In this report, we described a 75-year-old Japanese case of recurrent, tumor mutation burden-high CAS on the scalp treated with pembrolizumab. Our present case survived for 1 year despite of taxane refractory CAS with mediastinal lymph node metastasis, though the administration of anti-PD-1 Abs alone could not fully suppress the tumor progression of CAS.
CONCLUSION: Since various factors such as pro-angiogenic molecules are correlated with the tumor progression in CAS, the administration of anti-PD-1 Abs alone could not fully suppress the tumor progression of CAS. Further novel anticancer drugs are needed in the future for the treatment of CAS.

ABSTRACT
A 86-year-old man presented with a 2-month history of epigastric pain. The patient denied nausea, vomiting, hematochezia, or hematemesis. Physical examination on admission showed tenderness beneath the xiphoid process, with a palpable hard mass. Abdominal CT revealed a huge irregular inhomogeneous low density mass between liver and stomach, with moderate enhancement.

ABSTRACT
Primary cardiac tumors are exceptionally rare, with malignant tumor occurrences ranging from 0.0017% to 0.28%. Among these, primary cardiac angiosarcoma (PCA) stands as the most prevalent malignancy, primarily impacting the right cardiac system. In this case report, we present the instance of a 44-year-old woman who recently exhibited acute chest discomfort and was subsequently diagnosed with a microangiosarcoma within the right atrium and superior vena cava. Diagnostic modalities including chest x-rays, CT, MRI, and PET-CT were instrumental in pinpointing the tumor's location and nature. Surgical excision followed by pathological and immunological examinations confirmed the diagnosis. The patient's recovery post-surgery has been encouraging, with successful follow-up chemoradiotherapy administered. Despite advancements, devising optimal strategies for enhancing patient survival and quality of life in angiosarcoma cases remains a pressing research challenge.

ABSTRACT
A 70-year-old man with supraglottic carcinoma underwent computed tomography (CT) for staging purposes. A tumor measuring approximately 7 × 10 cm was found incidentally in the left perirenal space. The tumor showed homogeneous high signal intensity on chemical shift subtraction magnetic resonance imaging (CSS-MRI) suggesting the presence of minimal amounts of fat. Five months later, the tumor had grown to approximately 10 × 12 cm with indistinct margins. CSS-MRI showed high signal intensity in the tumor periphery only. The tumor was resected and the pathological diagnosis was angiosarcoma. Angiosarcomas are malignant endothelial vascular neoplasms that are highly invasive to their surroundings. Here we report a case of primary perirenal angiosarcoma that was difficult to differentiate from a dedifferentiated liposarcoma. On CSS-MRI, high signal intensity within a tumor may be a characteristic feature of primary perirenal angiosarcoma.

ABSTRACT
A 5-year-old intact female Shih Tzu was presented with acute onset of hind leg paralysis. The neurologic examination revealed severe T3-L3 myelopathy. The differential diagnoses included degenerative, anomalous, traumatic, inflammatory, vascular, metabolic, and neoplastic changes. The results of the paraclinical examinations and diagnostic imaging narrowed the list of differential diagnoses and, along with the patient's deteriorating condition, led to the owner's decision to euthanise the dog. The histologic findings of the spinal cord specimens indicated a tumour of the blood vessels formed by the proliferation of endothelial cells, which may present as either capillary or cavernous structures. In this case, the tumour was a capillary-type haemangiosarcoma. The primary site of proliferation could not be determined in this case because no mass formation was noted while performing the necropsy.

ABSTRACT
BACKGROUND: Only 27 cases of equine conjunctival haemangiosarcoma have been reported in the literature over the past 37 years. Out of these, 22% of cases were lost to follow-up, 52% were euthanized, and 26% survived. A scarcity of cases and information is available for this rarely seen conjunctival tumour.
AIM: To describe the clinical features, management, and outcome of conjunctival hemangiosarcoma in seven horses in the UK.
METHODS: Optivet medical records were reviewed for equine cases seen or advised on with a histopathological diagnosis of conjunctival haemangiosarcoma between January 2013 and March 2023. Medical records were accessed for details of signalment, history, management, and follow-up. Histopathology was used to confirm the diagnosis of haemangiosarcoma and assess the surgical margins. Immunohistochemistry was performed in a minority of cases with poorly differentiated solid tumours to support vascular lineage.
RESULTS: Seven eyes from seven horses (five geldings and two mares) with a mean age of 16 years and median of 18 years (range 10-21 years) met the criteria. Serosanguinous discharge was seen in six eyes. All eyes were managed surgically; 4 by exenteration and 3 by conjunctivectomy/keratectomy. Adjunctive cryotherapy was performed in two eyes. Metastatic disease in the ipsilateral parotid salivary gland, confirmed with histopathology, was seen in one horse. Surgical margins were clear in all but one eye. Solar elastosis was noted in five eyes. All horses were healthy at the last follow-up (0.2-5 years, mean 2.9 years, and median 2 years).
CONCLUSION: Equine conjunctival haemangiosarcoma is rare. Serosanguinous ocular discharge is a common clinical sign. Early surgical excision is highly effective. Solar elastosis is a common histopathological feature, suggesting a role for UV-light in the pathogenesis.

ABSTRACT
In silico toxicology protocols are meant to support computationally-based assessments using principles that ensure that results can be generated, recorded, communicated, archived, and then evaluated in a uniform, consistent, and reproducible manner. We investigated the availability of in silico models to predict the carcinogenic potential of pregabalin using the ten key characteristics of carcinogens as a framework for organizing mechanistic studies. Pregabalin is a single-species carcinogen producing only one type of tumor, hemangiosarcomas in mice via a nongenotoxic mechanism. The overall goal of this exercise is to test the ability of in silico models to predict nongenotoxic carcinogenicity with pregabalin as a case study. The established mode of action (MOA) of pregabalin is triggered by tissue hypoxia, leading to oxidative stress (KC5), chronic inflammation (KC6), and increased cell proliferation (KC10) of endothelial cells. Of these KCs, in silico models are available only for selected endpoints in KC5, limiting the usefulness of computational tools in prediction of pregabalin carcinogenicity. KC1 (electrophilicity), KC2 (genotoxicity), and KC8 (receptor-mediated effects), for which predictive in silico models exist, do not play a role in this mode of action. Confidence in the overall assessments is considered to be medium to high for KCs 1, 2, 5, 6, 7 (immune system effects), 8, and 10 (cell proliferation), largely due to the high-quality experimental data. In order to move away from dependence on animal data, development of reliable in silico models for prediction of oxidative stress, chronic inflammation, immunosuppression, and cell proliferation will be critical for the ability to predict nongenotoxic compound carcinogenicity.

ABSTRACT
Breast cancer is the most prevalent form of cancer worldwide. Every year, it affects a significant number of women in the UK and is considered one of the leading causes of cancer-related deaths globally. While breast cancer is primarily linked to adult women, its occurrence in children and adolescents is exceedingly rare. This study conducted a narrative review spanning from 1999 to 2023, examining 32 case reports to investigate the characteristics of breast cancer in the paediatric age group. These reports focused on patients under 18 years old who were diagnosed with primary glandular breast cancer, excluding cases originating from other tissues like angiosarcoma, leukaemia, and metastatic cancer. The data analysis encompassed various parameters, including gender, age, histology, receptor status, lymph node involvement, treatment methods, and genetic characteristics. From the published case reports, it was concluded that the most common type of breast cancer affecting children and adolescents is secretory breast carcinoma and predominantly occurs in females. It is typically hormone receptors negative, and the preferred treatment approach involves mastectomy as breast conservation surgery to preserve the developing breast tissue is a real challenge due to limited breast tissue volume in this age group.

ABSTRACT
Angiosarcoma is a rare type of soft tissue cancer with several clinical presentations and a poor prognosis. We present a case of a 75-year-old man who was admitted due to anemia and fatigue. The patient had undergone an endovascular repair (EVAR) of a 9 cm infrarenal aneurysm of the abdominal aorta two months ago. A computed tomography (CT) scan of the abdomen on admission indicated a Type-II endoleak and a large hematoma of the left psoas muscle with multiple sites of intramuscular extravasation. Osseous metastases were found at the head of the left femoral head and at the iliac bones. A CT guided biopsy of the femoral head revealed an angiosarcoma of unknown primary site a few days after the patient had died from intra-alveolar hemorrhage caused by lung metastases.

ABSTRACT
Cutaneous angiosarcomas are rare soft tissue tumours originating from hematogenous vasculature that are aggressive and carry a poor prognosis. We describe the case of a 73-year-old man with a low-grade well-differentiated angiosarcoma. Our case distinguishes itself from those previously reported in the slow progression and important delay to the presentation of 30 months and survival time of 5.5 years. Additionally, its severe clinical appearance (T2 stage) but milder pathological picture (T1 stage) is very uncommon. A repeat biopsy is warranted when results are inconclusive and there is a high clinical suspicion of angiosarcoma.

ABSTRACT
Massive localized lymphedema (MLL) is an emerging clinical phenomenon predominantly observed in morbidly obese individuals. It presents both diagnostic and therapeutic challenges to clinicians due to its characterization by large, pendulous masses in the abdomen or thigh. MLL may resemble malignant conditions, such as liposarcoma, leading to unnecessary invasive interventions. This study presents two case studies: a 74-year-old male who succumbed to postoperative complications and a 56-year-old female who experienced successful recovery. These cases highlight the urgent need for robust diagnostic criteria and evidence-based management approaches for MLL. In addition, further research exploring the pathogenesis, risk factors, and potential connections among MLL, hypothyroidism, and angiosarcoma is essential.

ABSTRACT
Scalp angiosarcoma (SA) is rare, accounting for <1% of soft tissue sarcomas, with a high degree of malignancy, a high recurrence rate and a poor prognosis. The best treatment strategy is uncertain. Therefore, it is essential to continuously refine treatment strategies and improve the prognosis of patients. Curative-intent surgery increases overall survival in patients with primary cutaneous angiosarcoma of the scalp and face, and radiation therapy combined with chemotherapy is now recommended for the curative treatment of patients who both can or cannot undergo surgery. The present case report is of an 87-year-old man hospitalised for the fifth time with SA. He had experienced four recurrences and previously underwent curative-intent surgery four times. However, the patient did not undergo radiotherapy or chemotherapy after any of the surgeries. A detailed report of the management of this case is presented along with a review of the relevant literature. It is hypothesised that patients with SA should receive a combination of radiotherapy and chemotherapy after surgery whenever possible, which may improve patient prognosis.

ABSTRACT
BACKGROUND: Primary angiosarcomas of the breast are rare and highly aggressive. We herein report a rare case of multiple angiosarcomas detected concurrently in both breasts.
CASE PRESENTATION: A 49-year-old woman visited a doctor after noticing a lump in her right breast. At that time, mammography and ultrasonography revealed no abnormal findings in either breast. She was referred to our hospital 5 months later, because screening mammography had revealed a focal asymmetric density in her right breast. Ultrasonography showed ill-defined hyper- and hypo-echoic lesions in both breasts. Magnetic resonance imaging disclosed five heterogeneously enhanced masses (5.8 cm in maximum diameter) in the right breast and six enhanced masses (approximately 1-3 cm in diameter) in the left breast. Histological examination of core needle biopsies revealed proliferation of irregularly shaped vascular channels lined by atypical endothelial cells throughout the adipose tissue and lobules of the breasts, leading to a diagnosis of well-differentiated angiosarcoma. The lesions were assumed to be primary angiosarcomas, because she had neither a history of breast surgery nor of radiation therapy. She underwent bilateral mastectomies and postoperative chest wall irradiation. Computed tomography 11 weeks after the surgery revealed multiple, small, subcutaneous nodules in the chest wall that were suspected of being angiosarcoma metastases. We started chemotherapy (weekly paclitaxel 80 mg/m2), which achieved shrinkage of these nodules within 2 months.
CONCLUSIONS: Early diagnosis, immediate initiation of local and systemic therapies, and intensive follow-up are important in improving the prognosis of angiosarcomas.

ABSTRACT
Primary splenic angiosarcoma is a very rare disease that causes the development of malignant tumors in the vascular endothelium of the splenic sinuses. Moreover, the disease maintains a very low survival rate for patients to live over 5 years, which is relatively low when compared to another splenic cancer, splenic lymphomas. The treatment options for splenic angiosarcoma narrow down to surgical removal or radiation combined with chemotherapy, but both cost a lot, so discovering potential alternative treatments may eventually increase the possible survival rate. Ginseng and Zhi Gan Cao are both common herbs in Traditional Chinese Medicine (TCM); however, the price of Ginseng is much higher than that of Zhi Gan Cao. A possible reason could be the frequent studies and researches over Ginseng's active ingredient, ginsenoside rh2 or rg3 as they are both potent cancer treatments. The reason to study Zhi Gan Cao and predict its possible potential in cancer treatment is due to the similarity between its active ingredient and the active ingredient in Ginseng, namely, ginsenoside rh2 and licorice saponins. Both TCM contain the active ingredient, triterpenoid saponin, as their main composition, and the further text will predict the possible research and results that may be taken in vitro to reveal the question of whether licorice saponin has the potential to become a major treatment for splenic angiosarcoma or not.

ABSTRACT
Combined modality therapy, including radiotherapy (RT), is a common treatment for scalp or face angiosarcoma. Although intensity-modulated radiotherapy (IMRT) can deliver homogeneous doses to the scalp or face, clinical data are limited. This multicenter study aimed to evaluate scalp or face angiosarcoma treated with definitive or post-operative IMRT. We retrospectively analyzed data from patients who received IMRT for scalp or face angiosarcoma at three institutions between January 2015 and March 2020. Local control (LC) rate, overall survival (OS), progression-free survival (PFS), recurrence patterns and toxicity were evaluated. Fifteen patients underwent IMRT during the study period. Definitive RT was performed on 10 patients and post-operative RT was performed on 5 patients. The 1-year LC rate was 85.7% (95% confidence interval [CI], 53.9-96.2%). The 1-year OS and PFS rates were 66.7% (95% CI, 37.5-84.6%) and 53.3% (95% CI, 26.3%-74.4%), respectively. Univariate analysis revealed that a clinical target volume over 500 cm3 was associated with poor LC. Distant metastasis was the most common recurrence pattern. All patients experienced Grade 2 or 3 radiation dermatitis, and five patients experienced grade ≥ 3 skin ulceration. One patient who underwent maintenance therapy with pazopanib developed Grade 5 skin ulceration. Fisher's exact test showed that post-operative RT was significantly associated with an increased risk of skin ulceration of grade ≥ 3. These results demonstrate that IMRT is a feasible and effective treatment for scalp or face angiosarcoma, although skin ulceration of grade ≥ 3 is a common adverse event in patients who receive post-operative RT.

ABSTRACT
A 7-year-old intact Netherlands Dwarf rabbit with bloody discharge from the vulva underwent ovariohysterectomy. Grossly, both sides of the uterus were enlarged. Histologically, the tumour had formed protruded from the myometrial wall toward the serosa and was composed of irregular small capillaries with irregularly shaped structures and bundled proliferation of spindle-shaped cells. No tumour cells infiltrated the endometrium. The tumour cells were positive for CD31, and histological and immunohistochemical staining confirmed the diagnosis of haemangiosarcoma. Vascular tumours in the uterus of animals are uncommon, and only one case has been reported in the uterus of rabbits.

ABSTRACT
Angiosarcoma is a rare and aggressive vascular malignancy that typically originates in the skin or soft tissue of the body. It is known to have a propensity for metastasis to the lung parenchyma in the form of pulmonary nodules and cavitary lesions; however, a less commonly described entity is in the form of a malignant pleural effusion. Management of a malignant pleural effusion due to angiosarcoma presents a unique challenge. This article describes the challenges faced during one patient's diagnostic and treatment course, and the anticipated future complications of his aggressive disease.

ABSTRACT
Angiosarcoma is the most invasive and malignant cardiac tumor and most commonly originates from the right atrium. Early diagnosis is essential, and echocardiography has an important role in diagnosis. This tumor grows aggressively, and metastases to other sites makes it difficult to control. Surgical treatment remains the best option for patients who do not respond to chemoradiotherapy. We herein report a case of a 17-year-old patient with cardiac angiosarcoma who presented with dyspnea, chest pain, dry cough, and fever. Although we considered the most probable diagnosis to be constrictive pericarditis, pathologic examination revealed a primary angiosarcoma originating from the pericardium. The patient underwent total pericardiectomy. However, despite receiving chemotherapy for 2 weeks postoperatively, she developed complications including leukopenia and eventually died of respiratory failure. Late diagnosis of angiosarcoma often occurs, resulting in progression to end-stage disease and a very poor prognosis. Therefore, a thorough understanding of this entity, knowledge of its pitfalls in management, and establishment of an accurate treatment guideline would help to develop a reliable and life-saving treatment approach for these patients.

ABSTRACT
Malignant tumors of the external auditory canal (EAC) are rare neoplasms that appear in the head and neck area. A common feature of these malignancies is their rarity, as well as their delayed diagnosis due to the appearance of non-specific symptoms that mimic various benign otologic conditions. The reported histological types of cancer of the external ear are: squamous cell carcinoma, basal cell carcinoma, malignant melanoma, Merkel cell carcinoma, angiosarcoma, adnexal carcinoma (including ceruminous adenocarcinoma and adenoid cystic carcinoma), and lymphoma (Lancet Oncol. 2005;6:411-20. doi: 10.1016/S1470-2045(05)70208-4). Several therapeutic interventions have been proposed, primarily orientated towards the cure of the patient, placing the surgical excision of the lesions at the tip of the spear. Subsequently and depending on the clinical stage and the pathological characteristics of the tumor, radiation, chemotherapy, a combination thereof, or some form of palliative treatment for particularly advanced cases, may be recommended. The aim of all the above-mentioned approaches is the complete resection of the mass with negative surgical margins along with lymph node dissection, the elimination of any residual disease or metastasis, and the improvement of survival. The anatomical complexity of the region will always remain a demanding challenge. Nevertheless, advances in the fields of ear microsurgery, imaging, radiation, molecular biology, and genomics have led to remarkable outcomes compared to the past, with a view to the patient's quality of life. Large, well-organized, and prospective studies with the participation of multiple centers in contrast to existing retrospective studies with a limited number of patients will help to establish universally accepted guidelines. The exploration of the molecular and genetic background of these cancers in conjunction with the search for new biomarkers and target molecules seems promising for providing upgraded and more personalized treatment modalities for the future.

ABSTRACT
BACKGROUND: Xeroderma pigmentosum (XP) is a rare autosomal recessive disorder presenting with an inability to repair UV-induced DNA damage. This can lead to the development of neoplasms affecting multiple organ systems, with onset often in childhood. Unfortunately, no cure currently exists for XP, and management strategies focus on sun protection and early intervention for malignancies. Although most skin problems in XP patients are UV induced, various oral lesions are also described. However, the literature has not extensively characterized the oral manifestations and their prognostic significance.
METHODS: We conducted a comprehensive review to evaluate the prevalence and nature of oral mucosal lesions in pediatric XP patients.
RESULTS: Our literature search yielded 130 pediatric XP patients with oral involvement and 210 associated tumoral or non-tumoral lesions. Squamous cell carcinoma was the most common type of oral mucosal tumor reported, with other malignancies including basal cell carcinoma, melanoma, angiosarcoma, fibrosarcoma, and trichilemmal carcinoma.
CONCLUSION: Given the potential morbidity and mortality associated with oral mucosal tumors in XP patients, our study aims to raise awareness of these manifestations. Early diagnosis and treatment are crucial for managing these lesions effectively, and routine oral exams should be considered a critical component of dermatological evaluations for XP patients, especially in the pediatric age group.

ABSTRACT
BACKGROUND: Masson's tumor, commonly referred to as intravascular papillary endothelial hyperplasia (IPEH), is an uncommon growth of endothelial cells within a vessel wall that is frequently assumed to indicate an abnormal resolution of thrombosis. IPEH is most typically found in the extremities however it is rare for IPEH to appear as a neck tumor. The issue with IPEH is that it could clinically, radiologically, and pathologically imitate some malignant neoplasms such as angiosarcomas creating a diagnostic challenge.
CASE REPORT: We describe a 21-year-old male patient who presented with right anterolateral neck swelling for 12 months. Ultrasound revealed a 9.0 × 8.0 cm well-defined echogenic hyper-vascular lesion. The contrast computed tomography (CT) scan of the neck revealed an oval, well-defined subcutaneous mass, measuring 9 × 4.5 cm, situated over and separable from the right sternocleidomastoid muscle with no significant enhancement in the post-contract study. T1-weighted and T2-weighted MRI revealed a 10 × 9 × 7 cm well-defined subcutaneous lobulated lesion superficial to the sternocleidomastoid expanding upward to the Rt. side of the cheek and below to the suprasternal region, eliciting an intermediate signal in T1 and a heterogenous bright signal (mostly fluid) in T2 with low signal foci within the mass. The decision had been reached to entirely excise the lesion surgically with safety margins for histological evaluation. Histological examination indicated thrombosed variable-sized ectatic vascular spaces with papillary formations related to the thrombus, covered with a single layer of flat endothelium, and no features suggestive of malignancy. There was no recurrence at 18 months follow-up post-surgery.
CONCLUSION: Masson's tumor is a benign intravascular disease with an unclear origin and no confirmed inheritance pattern. Presentation of Masson's tumor as a neck mass is incredibly uncommon. Masson's tumor lacks a distinct or distinguishing clinical and radiological appearance. Histopathologic examination is the sole definitive way for diagnosing the disease and the only tool for distinguishing it from angiosarcoma. Surgical excision is the best treatment for IPEH. Recurrence is extremely rare.

ABSTRACT
BACKGROUND: Anastomotic hemangioma is a rare subtype of capillary hemangioma primarily found in the genitourinary tract. We present a case of a patient with an anastomotic hemangioma located in the retroperitoneal space; then, we explore and summarize the imaging features from previously reported cases for accurate diagnosis.
CASE PRESENTATION: A 57-year-old woman complained of left lower back pain. Contrast-enhanced ultrasound revealed a hypoechoic mass with "slow-in and slow-out" enhancement. Abdominal CT scan displayed a well-defined, round soft tissue mass in the right retroperitoneal region with obvious enhancement. MRI indicated low signal on T1-weighted imaging, high signal on T2-weighted imaging and diffusion-weighted imaging, and progressive enhancement after enhancement. Surgical removal of the tumor was performed. Histopathological examination exhibited a distinct tumor border with interconnected blood vessels and a cavity lined by a single layer of cubic endothelial cells. Immunohistochemistry confirmed the presence of CD31[+] and CD34[+]. The final pathological diagnosis was anastomotic hemangioma. No recurrence was observed during a 40-month follow-up.
CONCLUSION: Retroperitoneal anastomotic hemangioma is a rare and benign neoplasm that may be misdiagnosed as ectopic pheochromocytoma or angiosarcoma. This case report presents and analyzes the imaging characteristics of a series of retroperitoneal anastomotic hemangiomas, which can be valuable for future diagnoses and help prevent unnecessary surgeries.

ABSTRACT
Vascular tumors of the liver are mesenchymal lesions from endothelial cells. They range from common benign lesions such as haemangioma, intermediate tumors like Kaposi sarcoma, and perivascular epithelioid cell tumor to malignant tumors such as hepatic epithelioid hemangioendothelioma and hepatic angiosarcoma in adults. Pediatric vascular tumors of the liver also include benign, locally aggressive, borderline, and malignant masses with haemangiomas being the most common benign tumors and epithelioid hemangioendothelioma being an uncommon pediatric malignancy. The list of these lesions is completed by nodular regenerative hyperplasia, solitary fibrous tumour, and hepatic small vessel neoplasms (HSVN). Some of these tumors are uncommon and rare. This review article aimed to enumerate hepatic vascular tumors along with their imaging, histopathology, molecular findings for accurate diagnosis that can result in better management.
