Abstract

Ovarian choriocarcinoma may either be primary or metastatic from the uterus and oviduct. Gestational choriocarcinoma following an ectopic pregnancy of the ovary are usually pure in composition, however, the tumors which are nongestational and teratomatous in origin, frequently combine with other germ cell tumors such as dysgerminoma, immature teratoma, embryonal carcinoma, endodermal sinus tumor, or teratocarcinoma. Primary choriocarcinoma of the ovary is extremely rare and only occasional case reports are found in the literature. The authors reported a case of primary nongestational choriocarcinoma combined with immature teratoma which arose in an ovary of 17-year old female.
