Abstract |
Hydatidiform mole, characterized by abnormal fetoplacental development and placental villous trophoblast hyperplasia, results from genetically abnormal conception. Twin pregnancy consisting of hydatidiform mole (H-mole) and a coexisting fetus occurs with an estimated incidence of 1 per 10,000-100,000 pregnancies. There are several data which H-mole and a coexisting fetus can carry out viable fetus recently. However this unusual pregnancy has the risks of malignant change and severe medical complications, so it is a dilemma to decide continuation or termination of pregnancy. We present a twin pregnancy with partial H-mole and a coexisting fetus that occurred following IVF-ET, which was terminated at 16 weeks of gestation. |
