Introduction hydatidiform mole (hm) is part of a group of diseases classified as gestational trophoblastic disease (gtd), which originate in the placenta and have the potential to locally invade the uterus and metastasize.
Types gtd is the common name for five closely related tumours (one benign tumour, and four malignant tumours): the benign tumour hydatidiform mole here, first a fertilised egg implants into the uterus, but some cells around the fetus (the chorionic villi) do not develop properly. Molar lesions hydatidiform - complete - partial invasive mole complete hydatidiform mole round villous outline circumferential proliferation of trophoblast. Gestational trophoblastic disease encompasses several disease processes that originate in the placenta these include complete and partial moles, placental site trophoblastic tumors, choriocarcinomas, and invasive moles a diet deficient in animal fat and carotene may be a risk factor  more. Overview a molar pregnancy — also known as hydatidiform mole — is a rare complication of pregnancy characterized by the abnormal growth of trophoblasts, the cells that normally develop into the placenta.

Noun: 1 hydatidiform mole - an abnormality during pregnancy chorionic villi around the fetus degenerate and form clusters of fluid-filled sacs usually associated with the death of the fetus.
