摘要
Epithelioid trophoblastic tumor （ETT） of the uterus is a rare tumor introduced recently, which is distinct from placental site trophoblastic tumor （PSTT） and choriocarcinoma with the histological appearance of resembling low-grade squamous cell carcinomas. Definition and treatment of this disease is still not very clear because of its very low incidence and epithelioid trophoblastic lesions. ETT generally behaves in a benign fashion with metastatic and death rates about 25% and 10%, respectively, Here we report three cases of ETT, in which one had metastasis and eventually died from the disease.
