The patient presented in this case report was a 45-year-old female, with a Stage IIIA ovarian angiosarcoma combined with mature teratoma, that underwent debulking surgery and achieved complete remission for 11 months after six cycles of MAID chemotherapy (mesna, adriamycin/doxorubicin, ifosfamide, and dacarbazine). Thereafter, she had tumor recurrence with peritoneal seeding and massive pleural effusion; hence she received chemotherapy again. Although she had been undergoing a series of chemotherapies, the tumor continued to progress. Hence, she refused further chemotherapy since September 2012. Unfortunately, she passed away in January 2013 due to severe dyspnea with wide spread tumor progression. She had the longestsurvival period (31 months) and complete remission period than the other advanced primary ovarian angiosarcoma cases ever reported in the literature.
