Hydatidiform mole: A hydatidiform mole (molar pregnancy) is a

A hydatidiform mole (molar pregnancy) is a gestational trophoblastic disease. Ultrasonography is used to identify both complete and partial molar pregnancies. (See the image below.) Treatment consists of evacuation of the uterus by dilation and curettage. 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 ...

Gestational trophoblastic diseases (GTDs) are a spectrum of tumors and tumor-like conditions characterized by the abnormal proliferation of placental tissue. This proliferation can involve the villous or trophoblastic components of the placenta. GTDs are heterogeneous in presentation, both clinically and histopathologically, and are commonly associated with a ...
