Unusual location of ovarian mixed germ cell tumor.

Intra-abdominal unusual location of mixed germ cell tumor of ovary, which consisted of endodermal sinus tumor and immature teratoma components, has been reported. Patient was a 21-year-old girl with a chief complaint of abdominal pain and mass. Ultrasound and computed tomography scan showed lobulated cystic mass. Laparotomy was performed, and due to specific localization, in which tumor localized as a tumoral bridge between two ovaries, we just performed maximal fertility-sparing surgery by preserving ovaries, tubes, and uterus. After that, four courses of chemotherapy (bleomycin, etoposide, and cis-platinum) were done to cure her. The alfa-fetoprotein became negative after three courses of chemotherapy, and she is under observation for the time being.
