Abstract
Ovarian angiosarcoma (OA) is rare, with only sporadic cases reported in English literature. We performed a systematic review of cases published in the PubMed, Science Direct, and Google Scholar databases with the aim of describing the reported clinicopathological features of OA. Fifty-three articles that reported 60 patients were reviewed. Of the 60 patients, 7 (11.6 %) were diagnosed with secondary (metastatic) ovarian angiosarcoma and 53 (88.3 %) were diagnosed with primary ovarian angiosarcoma. The mean age at presentation for ovarian angiosarcoma was 38.3±17.8 years. The average tumor size for ovarian angiosarcoma was 11.9±6.1 cm. Abdominal distention was reported in 45/60 (75 %). Microscopic examination revealed necrosis in 28/60 (46.7 %), pleomorphism in 32/59 (54.2 %), mitotic figures in 44/60 (73.3 %), spindle-shaped cells in 27/36 (75 %), epithelioid-shaped cells in 20/36 (55.5 %), and mixed epithelioid and spindle-shaped cells in 12/36 (33.3 %) patients. On immunohistochemistry CD 31 was positive in 41/41 (100 %), CD 34 in 38/39 (97.4 %), and Factor VIII related antigen in 18/21 (85.7 %) patients. Metastasis was present in 43/60 (71.6 %) patients. Chemotherapy and surgery was performed in 36/52 (69.2 %). The median follow-up time for ovarian angiosarcoma was 7 months (IQR1-IQR3:2-13.5 months). 24 (48 %) of the 50 patients with available survival data were alive and 26/50 (52 %) were dead of disease. Survival analyses (KM curves) revealed that the presence of necrosis (log-rank test; p = 0.05) and absence of spindle-shaped cells (log rank test; p = 0.04) on histopathology were associated with worse outcomes, while treatment with combined chemotherapy and surgical excision was associated with better survival (P < 0.001) therefore, prompt diagnosis and early treatment with combined chemotherapy and surgical excision can prolong survival in OA.

Angiosarcoma Arising in Ovarian Mucinous Tumor: A Challenge in Intraoperative Frozen Section Diagnosis. Case Rep Pathol 2016; 2016:8508624.

Abstract
Angiosarcoma of the ovary is rare but represents an aggressive type of malignant ovarian neoplasms. The purpose of this report is to describe the features of angiosarcoma arising in mucinous tumor that was misinterpreted as a benign vascular proliferation during the intraoperative consultation. A 45-year-old woman presented with an abdominal mass for 1 month. Exploratory laparotomy was performed. A 35 cm right ovarian mass submitted for intraoperative consultation was a multicystic mucinous tumor with an 8 cm area of hemorrhagic lesion between cystic locules. The frozen section diagnosis was at least mucinous borderline tumor. The hemorrhagic area, which was intraoperatively interpreted as organizing vessels associated with previous hemorrhage, represented angiosarcoma in permanent sections. Angiosarcoma may present a challenge in intraoperative frozen section diagnosis of an ovarian mass. The presence of ectatic anastomosing vessels with dissecting growth appears to be the clue to a suspicion of angiosarcoma. The presence of endothelial atypia provides further support for the diagnosis. A macroscopic hemorrhagic area in an ovarian mucinous tumor should be evaluated with care, and the possibility of angiosarcoma should be borne in mind.

Abstract
Angiosarcoma is a rare and aggressive type of sarcoma, and primary angiosarcoma of the ovary is extremely rare. We report the case of a 29-year-old woman who was diagnosed with ovarian angiosarcoma and possible bone metastases. We treated this patient with a gemcitabine-based regimen as postoperative adjuvant chemotherapy, after which she achieved at least 7 years of progression-free survival, an extremely long duration given the aggressive features of this tumour. We retrospectively performed immunohistochemical analyses and fluorescence in situ hybridization to make a pathology diagnosis and to investigate the tumour features. MYC amplification and c-Myc protein overexpression were positively detected. It might be possible to correlate the effectiveness of the gemcitabine-based chemotherapeutic regimen with MYC gene amplification and c-Myc protein overexpression.

Abstract
OBJECTIVE Angiosarcomas are aggressive, malignant soft tissue neoplasms of endothelial origin and occur rarely in the female genital tract. There is lack of consensus on risk factors for poor outcome and optimal treatment. To this end, we performed a clinicopathologic review and survival analysis. METHODS We report a case of a woman with an angiosarcoma of the vagina. Published English literature was reviewed for angiosarcomas of the vulva, vagina, uterus, and ovary. Survival was evaluated by using Kaplan-Meier analysis and the effect of clinical and demographic variables on survival by using Cox regression analysis. RESULTS A total of 51 patients were identified with a median age of 47 years (range, 17-87 years). Two of the patients had an angiosarcoma of the vulva; 2 had an angiosarcoma of the vagina; 18 had an angiosarcoma of the uterus, and 29 had an angiosarcoma of the ovary. Five-year overall survival was 27% (SE, 8%). Most patients presented with locoregional disease, having surgery as their primary intervention. Overall, adjuvant therapy significantly improved survival (hazards ratio, 0.17; 95% confidence interval, 0.05-0.59; adjusted for age and tumor size). Adjuvant treatment consisted of radiotherapy for angiosarcomas of the vulva, vagina, and uterus and chemotherapy for ovarian angiosarcomas. Subgroup analysis of the female genital tract site was hampered by the small number of cases. CONCLUSIONS This review supports the use of surgical and adjuvant radiotherapy for angiosarcomas of the vulva, vagina, and uterus. Cytoreductive surgery and adjuvant chemotherapy remain the primary treatment of angiosarcomas of the ovary.

Abstract
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.

Abstract
Primary de novo angiosarcoma of the breast is an uncommon, aggressive neoplasm. Here, we present a case of a young woman who initially developed primary angiosarcoma of the breast, and subsequently angiosarcoma of the ovary during pregnancy two years later. Only two confirmed primary angiosarcomas of the breast metastasizing specifically to the ovary have been described in the literature. However, all previous cases had ovarian metastases at presentation or shortly after initial diagnosis. This case is unusual as it occurred after a relatively long interval, and apparently developed during pregnancy. We discuss this rare phenomenon, as well as the possible factors contributing to the recurrence.

Abstract
Primary angiosarcoma of the ovary (AS) is a rare entity with only 31 reported cases. The majority are pure angiosarcomas, the remainder are associated either with teratomas or conventional epithelial tumors. More than 50% of ovarian AS are disseminated at the time of diagnosis, the minority is detected in stage I. The prognosis of ovarian angiosarcoma in general is poor. Most reports refer to younger individuals, aged from 7 to 46 years, and only 2 case reports could be found for patients older than 64 years. Here we present a very unusual case of angiosarcoma in a 81-year-old patient.

Abstract
We report the case of a 39-year-old woman who presented with a pelvic mass extending into the upper abdomen. Transabdominal sonography revealed a complex left adnexal mass. Color Doppler imaging and spectral Doppler analysis showed increased vascularity with low impedance blood flow signals, suggestive of neovascularization. The patient underwent a laparotomy and a 56-kg predominantly cystic tumor was removed from the left adnexal region. The patient died 3 months later with pulmonary metastases and massive pulmonary hemorrhage. Postmortem resampling of the ovarian tumor initially diagnosed as mucinous cystadenoma showed nodular areas of malignant pleomorphic cells consistent with angiosarcoma.

Abstract
Mature cystic teratoma of the ovary is the most common ovarian tumor. Malignant transformation of this neoplasm is rare and is mostly represented by squamous carcinoma. Less frequently, malignant transformation is represented by a sarcoma. To date, only 5 cases of angiosarcoma arising in a mature cystic teratoma of the ovary have been reported. Herein, we report the clinicopathologic features of one such case. A review of the literature is also presented.

Abstract
BACKGROUND Sarcomas of the female genital tract are very rare. A small subset of these, primary ovarian angiosarcoma, is even more rare, with only 26 cases reported in the literature. Most cases of advanced-stage disease are aggressive and demonstrate a poor response to both surgery and chemotherapy with an overall poor prognosis. CASE We present a case of a previously healthy 67-year-old woman who presented with abdominal pain and profound anemia. She underwent a full staging and optimal debulking that revealed Stage IIIC primary ovarian angiosarcoma. The patient died 3 weeks post-operatively secondary to hemorrhage from progressive, metastatic tumor sites prior to initiation of chemotherapy. CONCLUSION Primary ovarian angiosarcoma is extremely rare, often presenting in later stages with nonspecific symptoms. Immunohistochemical staining of pathological specimens can aid in the diagnosis. The optimal regimen for adjuvant chemotherapy is unknown, and the prognosis is very poor.

Abstract
Benign and malignant somatic tumours arising in mature cystic teratomas of the ovary are a rare but recognised phenomenon. Squamous cell carcinoma is the most common somatic malignancy arising in ovarian teratomas, although many other types of tumour have been described. An angiosarcoma with "cutaneous" type typical features arising in a dermoid cyst of the ovary is reported. Vascular tumours have only rarely been described as secondary somatic tumours in ovarian teratomas. The diagnostic features and complications of such tumours are described.

Abstract
BACKGROUND Ovarian angiosarcomas are rare tumors which may to be distinguished from other unusual primary ovarian tumors such as clear cell carcinoma, yolk sac tumor and leiomyosarcoma on the basis of histological appearance and immunohistochemistry. Angiosarcomas of the ovary occur in all age groups but are more frequent in women of child bearing age (less than 40 years). Surgery and radiotherapy have been the traditional treatment modalities. CASE The case we present is the only reported long-term survivor of recurrent ovarian angiosarcoma. Her initial treatment was surgical, both at presentation and relapse but since she wished conservation of fertility, radical surgery and radiotherapy were avoided and she underwent further adjuvant chemotherapy with doxorubicin and ifosfamide. She remains in remission 6 years after treatment of recurrence of the primary tumor and has had a successful pregnancy following treatment. CONCLUSION Adjuvant chemotherapy of ovarian angiosarcoma with a combination of doxorubicin and ifosfamide appears effective and should be considered in women at risk of relapse who wish to conserve fertility.

Abstract
Primary angiosarcoma of the ovary is a rare tumor, with less than 25 cases reported in the literature. These tumors are thought to arise from carcinosarcomas, teratomas or the ovarian vasculature, and occur at any age. The prognosis is dismal in the majority of cases. We present the case of a 19-year old female who presented with abdominal distention and abdominal pain. Tapping of peritoneal effusion showed groups of pleomorphic cells that were negative for epithelial and germ cell markers. Immunohistochemistry performed on the surgical specimen of the ovary, and subsequently on the effusion specimen showed staining for endothelial markers. The patient was treated post-operatively with chemotherapy, but died one year following diagnosis. This is the first reported case of an ovarian angiosarcoma that metastasized to the peritoneal cavity, with a resulting malignant effusion. Despite the rarity of metastasis from gynecological sarcomas in effusions, this possibility needs to be included in the differential diagnosis of malignant effusions that are negative for epithelial and germ cell markers.

Abstract
P53: gene alterations correlate highly with advanced ovarian carcinoma in women. In mice, p53 deficiency predominantly results in the formation of lymphomas and sarcomas. However, ovarian epithelial tumors have not been documented in p53 homozygous mutant (p53-/-) mice, probably because they die before other tumors can form. To determine whether p53-/- ovaries can develop epithelial tumors, they were transplanted into the ovarian bursae of histocompatible wild-type recipient females. The p53-/- ovarian grafts formed tumors approximately 1 year post-transplantation. The tumor type was angiosarcoma, suggesting that vascular tissues are predisposed to tumor formation in p53-/-ovaries. These findings suggest that p53 deficiency alone is not sufficient for ovarian epithelial tumorigenesis in mice. Thus, other genetic lesions are likely required to develop mouse models of human ovarian cancer.

Abstract
A 45-year-old woman presented with a short history of abdominal distension and features of intestinal obstruction. Computed tomography examination of the abdomen revealed a solid and cystic mass in the region of the left ovary, but spread within the abdomen was also noted. The ovarian tumor was removed, and an omentectomy was also performed. Microscopic examination of the ovarian tumor and metastases within the omentum showed a carcinosarcoma composed of borderline serous papillary cystadenocarcinoma and angiosarcoma. The angiosarcomatous component was the dominant tumor within the omentum. This case documents an unusual combination of epithelial and sarcomatous elements in an ovarian carcinosarcoma. The tumor behaved aggressively because of the angiosarcomatous component, and since the patient was assessed as having stage IV disease, no further treatment was offered.
