Definition:
A condition where a molar pregnancy, such as a partial hydatidiform mole or complete hydatidiform mole, invades the wall of the uterus, potentially spreading and metastasizing to other parts of the body (such as the vagina or lungs).
Invasive moles occur in about 20% of molar pregnancies but are more common in complete molar pregnancies than in partial molar pregnancies. Invasive moles can develop both before and after treatment by D & C. Treatment of an invasive mole may include chemotherapy.
Also Known As: Persistent Gestational Trophoblastic Disease (one of three types)
