Abstract

Placental site trophoblastic tumor (PSTT), a rare variant of gestational trophoblastic disease, was first described in 1976. PSTT is usually seen in young women, generally treated by hysterectomy, and is associated with a 20% fatality rate. The development of metastases secondary to PSTT is associated with an extremely poor prognosis. Metastatic PSTT has generally been resistant to chemotherapy although one complete and some partial responses have been noted previously. We report a case of a complete chemotherapeutic response in a patient with pulmonary metastases.
