A complete hydatiform is a type of molar pregnancy.
A molar pregnancy is a gestational trophoblastic disease that grows into a mass in the uterus with hydropic chorionic villi. On ultrasound, the mole resembles a bunch of grapes ("cluster of grapes" or "honeycombed uterus" or "snow-storm"). Hydatidiform moles should be treated by evacuating the uterus by uterine suction or by surgical curettage as soon as possible after diagnosis, in order to avoid the risks of choriocarcinoma. Patients are followed up until their serum human chorionic gonadotrophin (hCG) level has fallen to an undetectable level. More than 80% of hydatidiform moles are benign. The outcome after treatment is usually excellent. Close follow-up is essential. Highly effective means of contraception are recommended to avoid pregnancy for at least 6 to 12 months. In 10 to 15% of cases, hydatidiform moles may develop into invasive moles and in less than 5% of cases, hydatidiform moles may develop into choriocarcinoma.
