Molar pregnancy with a coexistent fetus following assisted reproductive techniques: Two case reports

Hydatidiform mole with the coexisting live fetus is a rare entity occurring in 0.005%–0.01% of all pregnancies. With the introduction of assisted reproductive techniques (ARTs), a significant rise in the incidence of multiple pregnancies has been reported. Here, we report two cases of molar pregnancies with a coexisting live fetus conceived following assisted conception. In our first case, pregnancy was continued and delivered a term live infant. The second case was aborted at 16 weeks' gestation due to maternal complications. These two patients needed chemotherapy due to persistent gestational trophoblastic disease. The rarity of this condition poses several diagnostic and management challenges, especially conceiving after ART the decision of termination for such couples.
