Abstract

A 36-year-old woman presented with a history of prolonged menstrual period and increased menstrual volume of 4 months. Ultrasonography showed inhomogeneous echo measuring 2.5×1.9×2.2 cm3 in uterine cavity, and it can be seen that the blood flow signal enters the uterine posterior wall. Trophoblastic disease was not ruled out. But the serum β-human chorionic gonadotropin (hCG) was <0.3 mIU/mL. In order to confirm the diagnosis, the patient was planned to undergo hysteroscopy. Hysteroscopy is an ideal solution for early diagnosis. However, the drawback of hysteroscopy is that only local lesions can be removed. If the infiltration degree is deep, a second hysterectomy is required. Our authors present the first case of epithelioid trophoblastic tumor (ETT) under hysteroscopy. After neoplasm partial resection, histopathological examination revealed ETT. The patient underwent hysterectomy to prevent recurrence.
