Abstract

  Placental site trophoblastic tumor (PSTT) is the rare variant of gestational trophoblastic diseases (GTD), which differs histologically and immunologically from GTD. Diagnosis of PSTT is often difficult and delayed. In most cases, diagnosis is not possible until the surgery is performed. The most therapeutic choice is hysterectomy and it is usually successful. Here we report two cases of PSTT.
