Complete Hydatidiform Mole
Medically reviewed by Drugs.com. Last updated on Apr 6, 2025.
A complete hydatidiform mole happens when cells turn into abnormal tissue in the uterus. The cells normally form the placenta. The tissue is a cluster of fluid-filled cysts that look like grapes. The cluster continues to grow and fill the uterus. The abnormal tissue is not cancer but may become cancer. A complete hydatidiform mole is also called a complete molar pregnancy. With a complete molar pregnancy, there is no fetus.
