Epithelioid trophoblastic tumour: a report of two cases

Abstract

An epithelioid trophoblalstic tumour (ETT) is an extremely rare form of gestational trophoblastic disease (GTD). 1 Usually, patients are of child-bearing age with a prior gestation. 2 The uterus is the most common site for an ETT. 3 This tumour has the same clinical behaviour as that of a placental site trophblastic tumour, but the treatment options may differ. Histologically, an ETT is a distinct neoplasm whose cytological features and growth patterns mimic those of squamous cell carcinoma. 3 An ETT does not appear to be as chemosensitive as other GTDs, making hysterectomy the treatment of choice in patients with disease confined to the uterus. 3 This tumour may present a diagnostic challenge to the pathologist, while clinicians often face problems with treating this tumour because of its rarity. We describe two cases of an ETT occurring in two women, one aged 44 years and the other 42 years.
