title: Gonadotropin-producing benign cystic teratoma simulating a ruptured ectopic pregnancy.
abstract: Benign cystic teratomas are asymptomatic in many cases. There are some reports of production of thyroid-stimulating hormone, estrogen, testosterone, and prolactin by these tumors. This article reports a patient in whom a twisted cystic teratoma simulated ruptured ectopic pregnancy by beta human chorionic gonadotropin production and hemorrhage into the peritoneal cavity.
