Nongestational pure ovarian choriocarcinoma is an uncommon condition and accounts for less than 0.6% of all ovarian tumors. It occurs most frequently as a component of a mixed germ cell tumor, and the presence of other germ cell elements establishes the nongestational origin of the tumor. Providing that a pure choriocarcinoma in the ovary is gestational in origin is difficult but important, as a primary germ cell tumor of the ovary is said to have worse prognosis and require more aggresive treatment. Here we report a case of primary nongestational choriocarcinoma in postmenopause woman with the review of literature.
