Complete hydatidiform mole

Description

A condition caused by the over-production of cells arising into the placenta during pregnancy. This condition is characterised by a pregnancy with abnormal placental growth in which the chorionic villi become hydropic, slight to severe trophoblast proliferation and invasion of the uterine tissue within 10-16 weeks after conception, a placental mass, 25-30% theca lutein cysts, 15-20% persistent trophoblastic disease, 50% uterine size for dates, and vaginal bleeding, nausea, or vomiting. This condition leads to an absent fetus.
