A molar pregnancy, also known as a hydatidiform mole, is an abnormal form of pregnancy in which a non-viable fertilized egg implants in the uterus. Learn about the possible causes, types and symptoms of this condition, as well as the risks of complications and treatment options. Hydatidiform mole is an abnormal pregnancy characterized by varying degrees of trophoblastic proliferation (both cytotrophoblast and syncytiotrophoblast) and vesicular swelling of placental villi associated with an absent or abnormal fetus/embryo. Two types of hydatidiform mole, complete and partial, have been described based on both morphologic and cytogenetic criteria (Table 1). 1,2 Epidemiology Epidemiologic studies have reported wide regional variations in the incidence of molar ... Overview A molar pregnancy is a rare complication of pregnancy. It involves unusual growth of cells called trophoblasts. These cells typically become the organ that feeds a growing fetus. That organ also is known as the placenta. There are two types of molar pregnancy — complete molar pregnancy and partial molar pregnancy. In a complete molar pregnancy, the placental tissue swells and appears to form fluid-filled cysts. There is no fetus. Known for its "grape-like" clusters due to swollen hydropic villi, hydatidiform moles are categorized into 2 types: complete and partial. A complete mole arises when an empty egg is fertilized by 1 or 2 sperm, resulting in a genome with only paternal DNA.
