Metastatic Angiosarcoma: A Rare Malignancy
European Journal of Clinical Medicine, 2021
Angiosarcoma is an infrequent vascular malignancy with grave prognosis due to distant metastasis at initial presentation. The predominant metastatic sites of angiosarcoma are lung; and it is particularly important and should be approached with multimodality treatment because pulmonary metastasis of angiosarcoma frequently induces severe complications. Here, we reported a case of angiosarcoma in an old Indian male presented with cough and hemoptysis. 18-FDG PET-CT scan revealed multiple organ involvement by tumor, and excisional biopsy from lung and pleural nodule revealed malignant tumor composed of spindle shaped epithelioid cell. Strong positivity for D2-40, CD 31 & CD 34 favoured the diagnosis of angiosarcoma. Patient was planned for intravenous chemotherapy with paclitaxel along with zoledronic acid. After 3-cycles of chemotherapy, re-evaluation with PET-CT revealed good response. In view of stable disease, it was planned to continue the same regimen for three more cycles. Howev...
Primary Splenic Angiosarcoma Revealed by Bone Marrow Metastasis
Turkish Journal of Hematology, 2014
Primary splenic angiosarcomas are the most common malignant non-hematopoietic tumors of the spleen. Metastatic diseases were found in 69% of patients in a reported series but the incidence of bone marrow involvement is unclear. We report a rare case of a 25-years-old Moroccan woman with unsuspected primary splenic angiosarcoma revealed by bone marrow metastasis. She presented with serious anemia and splenomegaly. Bone marrow biopsy revealed proliferating spindle cells. Computed tomography scanning showed an enlarged spleen with heterogeneous lesions. Splenectomy was performed and retrospective histological study of the spleen confirmed the diagnosis. She died 1 year after splenectomy.
Systemic therapy in primary angiosarcoma of the spleen
Rare Tumors, 2012
Primary splenic angiosarcoma is a very rare neoplasm with a high propensity for metastatic disease and poor prognosis. There is a paucity of literature concerning this specific sarcoma subtype and the role of systemic therapy is not well defined. A retrospective review of the prospectively maintained University of Washington/Seattle Cancer Care Alliance Sarcoma Unit database was performed to identify patients with splenic angiosarcoma treated between 2007 and 2012. In total there were 19 patients with angiosarcoma treated at the Seattle Cancer Care Alliance from 2007 to 2012. The number of patients with splenic angiosarcoma was 2 (11%). The first patient was a woman aged 57 years who was referred with metastatic splenic angiosarcoma to the liver, post-splenectomy. She was treated with 4 cycles of weekly paclitaxel prior to metastatic resection and 4 cycles of the same drug in an adjuvant scenario, achieving a pathological complete response to treatment. She is alive and on third-line systemic therapy. The second patient was a male patient aged 30 years who presented with metastatic high-grade splenic angiosarcoma and was treated with 3 lines of systemic therapy, including doxorubicin, paclitaxel and gemcitabine+docetaxel, but developed a gastrointestinal metastasis with subsequent gastrointestinal bleeding. Splenic angiosarcoma is a very rare neoplasm. Surgery remains the mainstay of management for localized disease. Paclitaxel administered weekly proved to be well-tolerated and resulted in a good radiological response in one of our patients, enabling resection of metastatic disease. Durable clinical benefit can be achieved in metastatic splenic angiosarcoma with multi modality management.

We describe the case of a 67-year-old female patient presenting with constitutional symptoms and rapid decline. Two bone marrow core biopsies were performed, with spindled cells identified and thought to represent marrow involvement by systemic mastocytosis on the first biopsy. A diagnosis of metastatic vascular malignancy with sarcomatoid features was favored on the second core biopsy. The patient rapidly deteriorated and passed away. The post-mortem examination revealed a splenic angiosarcoma with metastasis to the liver and bone marrow. Splenic angiosarcoma is a rare, aggressive entity, with bone marrow metastasis even more uncommon. This report perceives this as a diagnostic consideration on bone marrow biopsies with spindled cells and explores the diagnostic dilemma and overlapping features of systemic mastocytosis and angiosarcoma.

BACKGROUND-Angiosarcoma of bone is a rare high-grade malignant vascular tumor. The literature regarding treatment and outcome of patients with this tumor is limited. We performed a two-institutional retrospective study to analyze treatment and survival of patients with angiosarcoma of bone. PATIENTS AND METHODS-We reviewed patients with the histological diagnosis of primary angiosarcoma of bone treated from 1980 to 2009. Demographic details, histology, treatment and survival were reviewed. RESULTS-38 men, 22 women (median age 54 years). Most lesions occurred in the femur and the pelvis. Metastatic disease at presentation was diagnosed in 24 patients (40%). Forty-three patients underwent surgery, with 30 of them achieving surgical complete remission (SCR). Radiotherapy (RT) was applied to 17 patients, and chemotherapy (CT) to 13/35 and 15/22 patients with localized and metastatic disease, respectively. The 5-year overall survival (OS) was 20%: 33% for patients with localized disease and 0% for metastatic patients. Higher 5-year OS was reported for patients who achieved SCR (46%) than for
Cytologic features of angiosarcoma: A review of 26 cases diagnosed on FNA
Cancer Cytopathology, 2016
BACKGROUND: This study describes the cytologic features of 26 angiosarcomas diagnosed on fine-needle aspiration. METHODS: Twenty-six angiosarcomas from 20 patients were confirmed by cytomorphology and immunocytochemical (immunohistochemistry) positivity for at least 2 of 3 vascular markers. Specimens were examined for spindled/epithelioid/plasmacytoid single cells, 3-dimensional clusters, multiple prominent/bar-shaped nucleoli (5 times longer than their width), chromatin strands, abnormal mitoses, necrosis, and vasoformative features. RESULTS: Eight males and 12 females with a mean age of 52 years (range, 2-94 years) underwent aspiration of tumors in the following: soft tissue or skin/subcutis (n 5 10), bone (n 5 4), nodes (n 5 5), lung (n 5 2), liver (n 5 2), heart (n 5 1), parotid gland (n 5 1), and pleural fluid (n 5 1). An angiosarcoma diagnosis was rendered for 24 of the 26 cases (92%); 1 was diagnosed as "atypical cells, cannot exclude angiosarcoma," and another was diagnosed as a malignant vascular neoplasm. Abnormal mitoses were most frequent (85%), and they were followed by single malignant cells (81%: epithelioid [69%], spindled [62%], and plasmacytoid [19%]), 3-dimensional clusters (54%), multiple prominent (62%) or bar-shaped nucleoli (54%), and chromatin strands (31%). Vasoformative features, including hemophagocytosis (54%), cytoplasmic lumina/vacuoles (69%) containing red blood cells (54%)/neutrophils (31%), and endothelial wrapping (69%), were seen in 88%; 23% had all vasoformative features, 88% had at least 1, and 12% had none. CONCLUSIONS: Angiosarcomas show a range of cytomorphologic features that make them potentially recognizable on cytology. Although vasoformative features are highly suggestive, they are not specific for angiosarcoma and may be seen in some nonvascular neoplasms. Immunohistochemistry and a high index of suspicion are required for an accurate diagnosis.
Angiosarcoma of bone: a retrospective study of the European Musculoskeletal Oncology Society (EMSOS)
Scientific Reports
Angiosarcoma of bone (B-AS) is a rare malignant tumor of vascular origin. the aim of this retrospective study is to report on treatments and prognosis. Data were collected from the EMSOS website. 80 patients in 9 centers included: 51 male/29 female; median age 54 years (range 17 to 92); 56% with localized disease, 44% metastatic. Primary tumor surgery: 76% (30% amputation, 26% intralesional margins); radiotherapy (RT): 41%; chemotherapy (CT): 47% (56% in metastatic, 41% in localized cases). With a median follow-up of 31 months (range 40 to 309), 5-year overall survival (OS) was 27% (95%CI 16-30): 41% (95%CI 25-56) for localized patients, and 8% (95%CI 0-20) for metastatic (p = 0.002). In metastatic patients, 1 year OS was significantly influenced by chemotherapy response: 67% (95CI% 29-100) for those who responded or had stable disease (n = 7), and 18% (95CI% 0-41) for patients with progressive disease (n = 11), p 0.002. The surgical complete remission (SCR) status was pivotal in localized patients (5-year OS 45% for SCR, 17% no SCR, p = 0.03); also 5-year OS was significantly influenced by age and site of the tumor. After multivariate analysis, the addition of radiotherapy to surgery significantly influenced the disease-free survival (DFS) rate, whereas the use of chemotherapy lost the significance showed at the univariate analysis. Overall, patients with metastatic B-AS have a dismal prognosis, with a prolonged survival in case with a response to chemotherapy. experimental trials with more active systemic treatment regimens are needed. in patients with localized disease, the patient's age and site of the tumor are prognostic factors and any effort must be made to achieve an SCR status. No definitive conclusions can be drawn from our data on the use of adjuvant chemotherapy, while the use of adjuvant radiotherapy might improve DSf in patients surgically free of disease. Angiosarcoma of bone (B-AS) is exceedingly rare, accounting for less than 1% of all primary bone sarcomas, with the highest incidence between 50 and 70 years of age 1,4. The diagnosis of B-AS is challenging and represents the malignant end of the spectrum of CD31/ERG positive vascular tumors, including hemangiomas, hemangioendotheliomas, well-differentiated and poorly differentiated angiosarcomas 1-3 (Fig. 1). The disease might present as unifocal or with multifocal bone lesions, and it is usually associated with a poor prognosis 1-6. Given the rarity of B-AS, only scant information can be found in the literature, mostly reported in form of small series and case reports. No specific treatment guidelines or position papers are available, so the treatment of choice is based on data from other types of bone and soft tissue sarcomas 1,3-7. The role of chemotherapy and prognostic factors for
Surgical Case Reports, 2020
Background: Angiosarcoma of the breast is very rare and can be divided into primary and secondary angiosarcoma. Radiation-induced angiosarcoma (RIAS) is classified as secondary angiosarcoma. Diagnosis of RIAS is difficult due to its rarity, and the interpretation of pathological imaging is complicated. In the National Comprehensive Care Network (NCCN) guidelines, the first choice of treatment is surgery with negative margins. Adjuvant radiotherapy (RT) for close soft tissue margins should be considered. Preoperative or adjuvant chemotherapy of nonmetastatic disease is not recommended for angiosarcoma. We report a case of RIAS, which was impossible to diagnose with core needle biopsy (CNB) but was diagnosed by excisional biopsy. The patient was then administered adjuvant chemotherapy using conjugated paclitaxel (PTX). Case presentation: A 62-year-old woman noticed a tumor in her right breast. She had a history of right breast cancer and had undergone breast-conserving surgery, RT, and tamoxifen therapy 8 years previously. CNB, which was performed twice, was inconclusive. The tumor was surgically excised and pathological analysis yielded a diagnosis of angiosarcoma. She then underwent a right mastectomy. One month after she underwent right mastectomy, a nodule reappeared on the skin of her right breast, and excisional biopsy revealed recurrence of angiosarcoma. A few weeks later another nodule reappeared near the post-operative scar and excisional biopsy revealed recurrence of angiosarcoma. We assumed that surgical therapy was insufficient because the patient experienced relapse of angiosarcoma after complete mastectomy. After the second recurrence, we treated her with systemic chemotherapy using PTX. There was no evidence of recurrence 8 months after chemotherapy. Conclusion: Although angiosarcoma is difficult to diagnose, many patients have a poor prognosis. Therefore, prompt treatment intervention is desired. Moreover, there is little evidence regarding adjuvant therapy of angiosarcoma since it is a rare disease. We consider that adjuvant therapy helped to effectively prevent recurrence in the patient after complete excision.
Ovarian angiosarcoma: a case report and review of the literature
Journal of Medical Case Reports, 2014
Introduction: Sarcomas of the ovary can either be histologically pure or can represent components of a more complex tumor. Ovarian angiosarcomas are rare, and probably arise from carcinosarcomas, teratomas or the rich ovarian vasculature. To date, only two small case series have been published, one with four cases and the other with seven. Case presentation: A 41-year-old Saudi woman presented to our gynecological clinic with abnormal vaginal bleeding. The initial clinical diagnosis was left ovarian cyst. The results of the remainder of her abdominopelvic examination were normal. Peri-operatively, the left ovarian mass resembled a hemorrhagic solid tumor. It was sent for frozen sectioning, which revealed it was an undifferentiated neoplasm. The final histopathological examination showed a vascular neoplasm showing vasoformative arborizing channels of variable sizes and shapes lined by atypical endothelial cells with intact capsule. Areas of necrosis were seen, along with fused anastomosing solid vascular area. She was diagnosed as having an angiosarcoma of intermediate grade, International Federation of Gynecology and Obstetrics stage IA. Conclusions: Patients with ovarian angiosarcomas most commonly present with abdominal pain, however some patients present with distant metastases, often in the lungs. Spread beyond the ovary is present at the time of diagnosis in most reported cases, with disease progression within less than a year after diagnosis. Cases of advanced stage disease behave aggressively and demonstrate poor response to surgery and chemotherapy, with an overall poor prognosis. They have a tendency for local recurrence and metastases, and prognosis is hence poor; the reported five-year survival rate is 10 percent to 35 percent, however, cases confined to the ovary have survived up to nine years.
