A case of non-gestational choriocarcinoma arising in the ovary of a postmenopausal woman

Primary ovarian choriocarcinoma. arising from a germ cell is an extremely rare occurrence, especially in postmenopausal women, and the prognosis is poor. Non-gestational choriocarcinoma. of the ovary (NGCO) accounts for 0.6% or less of all ovarian neoplasms. It is important to distinguish gestational choriocarcinomas of the ovary (GCO) from other carcinomas because of the poor prognosis of NGCO. We describe a case of NGCO with lung metastasis in a 55 year old woman, which we present together with a brief review of the literature.
