Borderline serous cystadenocarcinoma with coexistent angiosarcoma: an unusual form of ovarian carcinosarcoma.
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.
