Placental site trophoblastic tumor associated with immature ovarian teratoma.

This paper describes a woman who developed three malignancies within a very short time. Two of these, immature teratoma and placental site trophoblastic tumor, were rare gynecological neoplasms. The third was a breast carcinoma. This is the first report of an association of placental site trophoblastic tumor with a primary germ cell tumor of the ovary.
