Hydatidiform Mole

Hydatidiform Mole (HM), also known as molar pregnancy, is an uncommon condition that occurs during pregnancy when there is an abnormal growth inside the uterus. It is a type of gestational trophoblastic disease (GTD), which involves abnormal growth of cells that would typically form the placenta during pregnancy.

The development of HM is attributed to an atypical egg (oocyte) fertilization, resulting in an abnormal pregnancy. In this condition, almost no fetal tissue develops, but the placenta continues to grow normally. The placental tissue surrounds a tumor within the uterus, which gives it a characteristic appearance resembling a cluster of grapes on ultrasound.
