Recurrent mixed germ cell-sex cord-stromal tumor of the ovary in an adult.

A 32-year-old woman underwent laparotomy and right salpingo-oophorectomy for a right adnexal mass. Examination of the specimen revealed a 77 g well-encapsulated tumor that was diagnosed as a mixed germ cell-sex cord-stromal tumor with annular tubules. Sixty-seven months after an uneventful recovery, a large recurrence was treated by total abdominal hysterectomy, left salpingo-oophorectomy, removal of peritoneal implants, lymphadenectomy, omentectomy, and chemotherapy. Histologically, the neoplasm was identical to the one found in the right ovary. To our knowledge, no similar case has been previously reported.
