[Trophoblastic gestational disease: a placental site trophoblastic tumor and an epithelioid trophoblastic tumor].

Placental site trophoblastic tumor and epithelioid trophoblastic tumor are rare gestational trophoblastic tumors. They both appear in the same context and follow the same course. We report two cases in patients aged 44 and 20 years. These lesions usually affect young women with a history of multiple gestations. Clinical manifestations include vaginal bleeding, uterine mass, and moderate elevation of serum beta human chorionic gonadotrophin levels. These morphologically distinct trophoblastic proliferations usually have a favorable course if complete excision is performed.
