The vast majority of cases arise in the uterus and represent gestational choriocarcinomas that derive from placental trophoblastic cells. Approximately half of the cases develop from a complete hydatidiform mole. A minority of cases arise in the testis or the ovaries. There is often marked elevation of human chorionic gonadotropin (hCG) in the blood. Choriocarcinomas disseminate rapidly through the hematogenous route; the lungs are most frequently affected."
