A tumor that forms in the uterus as a mass of cysts resembling a bunch of grapes. Hydatidiform moles occur during the childbearing years, and they do not spread outside the uterus. However, a malignancy called choriocarcinoma may start from a hydatidiform mole. In its early stages, a hydatidiform mole may look like a normal pregnancy. Diagnosis is based on a history of lack of fetal movement, a pelvic examination, an ultrasound, and a blood test to look for high
levels of the hormone beta human chorionic gonadotropin (hCG). hCG in the blood of a woman who is not pregnant can be a sign of a hydatidiform mole. Treatment includes removal of the mole by dilation and curettage (D & C) and suction evacuation and surgery to remove the uterus (hysterectomy). Also known as a molar pregnancy.
