2 introduction ❖Defination: gestational trophoblastic disease (GTD) is a group of disease originated from placental villose trophoblastic cells, including hydatidiform mole, invasive mole, choriocarcinoma and a kind of less common trophoblastic cell tumor in placenta

Those that invade locally or metastasize arecollectively known as gestationaltrophoblastic neoplasia (GTN).Hydatidiform mole is themost commonform of GTN. While invasive mole andchoriocarcinoma are malignant,ahydatidiform mole can behave in amalignant or benign fashion
