There are different types of GTD, each with distinct characteristics:
Complete Hydatidiform Mole: This is when there is an abnormal fertilization with no fetal tissue. The placenta grows in a mass of cysts. Partial Hydatidiform Mole: This occurs when two sperm fertilize an egg, resulting in abnormal fetal tissue alongside the molar tissue. Invasive Mole: This is a type of mole that penetrates into the muscle layer of the uterus and can cause severe bleeding. Choriocarcinoma: A highly malignant form that can spread to other parts of the body. Placental-Site Trophoblastic Tumor: A rare form that arises where the placenta attaches to the uterine wall.
