Ovarian choriocarcinoma may either to 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.
