Rare Case of Twin Pregnancy with Complete Hydatidiform Mole and Coexisting Fetus (CHMF) following Infertility Treatment.

Twin pregnancy consisting of complete molar pregnancy and a coexisting fetus occurs with an estimated incidence of 1 per 22,000–100,000 pregnancies, and may be increasing due to the greater use of assisted reproductive techniques [1]. These pregnancies are associated with significant maternal and fetal complications including preeclampsia, thromboembolic disease, hyperemesis, hemorrhage, intrauterine demise, and an increased risk of persistent trophoblastic disease. In this study, we report the case of twin pregnancy with a complete hydatidiform mole (CHM) that was managed conservatively according to the patient’s request and circumstances.
