hydatidiform mole

= hydatid mole; = vesicular mole
a collection of fluid-filled sacs that develop when the membrane (chorion) surrounding the embryo degenerates in early pregnancy with proliferation of the trophoblast. These sacs give the placenta the appearance of a bunch of grapes. The embryo dies, the uterus enlarges, and there is a discharge of pinkish liquid and cysts from the vagina; a characteristic ‘snowstorm’ appearance is seen on ultrasound. A malignant condition may subsequently develop (see choriocarcinoma).
