The value of endometrial curettage in the follow-up of hydatidiform mole

Multiple curettages in the follow-up of patients with hydatidiform mole are often performed in Sweden. Of 36 patients developing trophoblastic neoplasia after molar evacuation, 24 underwent one or more endometrial curettages. The objective was generally to verify a diagnosis of malignant disease. However, in only one patient was a histopathological proof of choriocarcinoma obtained. In 3 other patients, malignancy could not be ruled out. It is demonstrated that development of malignancy after hydatidiform mole is rarely proven by endometrial curettage.
