Placental-site trophoblastic tumor following metastatic gestational trophoblastic neoplasia

Abstract

Placental site trophoblastic tumor generally follows term pregnancy or nonmolar abortion. Thus far, 10 cases of placental site trophoblastic tumor have been described which were preceded by a hydatidiform mole. This is the first reported case where placental site trophoblastic tumor has been preceded by metastatic gestational trophoblastic neoplasia treated by chemotherapy.
