Abstract

Context.— Gestational trophoblastic tumors include 3 distinct entities: gestational choriocarcinoma, placental site trophoblastic tumor, and epithelioid trophoblastic tumor. Accurate diagnosis is important for clinical management of the patient. Objective.— To review clinical features and pathologic diagnosis of gestational trophoblastic tumors. Data Sources.— Literature and personal experience are the sources for this study. Conclusions.— Trophoblastic tumors are rare encounters in modern medicine, as a result of clinical practice of molar surveillance programs and early chemotherapeutic intervention for persistent gestational trophoblastic neoplasia. Diagnostic recognition of these tumors requires a high index of suspicion, awareness of their histologic characteristics, and appropriate application of immunohistochemical and molecular biomarkers. Recent attention has been given to a few precursor lesions of gestational trophoblastic tumors, including early/in situ choriocarcinoma and atypical placental site nodule.
