Mixed germ cell tumor of the ovary with a prominent polyembryoma component

Abstract

A mixed germ cell tumor of the ovary containing polyembryoma and abundant vascular tissue occurred in a 17-year-old woman. She underwent surgical resection of the tumor. Both 1 and 3 years after the original surgery, metastatic tumor deposits composed of mature and immature teratoma were excised from the abdominal cavity. Eleven years after her original surgery, she is living and well.
