title: Twin pregnancy with hydatidiform mole (46, XX) and a coexistent fetus (46, XY): report of a case.
abstract: Coexistent hydatidiform mole (46, XX) and live fetus (46, XY) in the second trimester is a rare phenomenon. In this case, the clinical manifestations presented as pregnancy-induced hypertension, including hypertension, proteinuria and oliguria. Ultrasonic examination found an enlarged placenta with a typical honeycomb picture, placenta previa and a normal developing fetus. The patient underwent an emergency cesarean section at 23 weeks' gestation on a preliminary diagnosis of acute chorioamnionitis. A 700 g immature male baby was delivered with Apgar scores of 3 at one minute, and 7 at five minutes. The placenta was composed of two parts: one was a molar pregnancy and the other was a normal placenta, both were separated by the membrane. The membrane consisted of one chorion and two amnions. Postmolar persistence of human chorionic gonadotropin was found one month after termination of this pregnancy. Chemotherapy with a single agent (methotrexate) was given. The patient is doing well and has no evidence of recurrence after one year of follow-up.
