Twin pregnancy of hydatidiform mole and viable fetus: a late diagnosis - case report / Gestação gemelar de mola hidatiforme e feto viável: um diagnóstico tardio - relato de caso

Twin pregnancy with hydatidiform mole and viable fetus is a rare event, evolving, in most cases, to abortion or medical interruption due the associated risks. Prenatal diagnosis allows individualized, rigorous and specialized monitoring, favoring the early identification of complications. We report, based on information obtained through medical record review, interviews with patient and professionals involved and literature review, a case of twin pregnancy with hydatidiform mole and healthy newborn diagnosed at delivery. Although the uncomplicated outcome that was presented suggests the possibility of expectant conduct, it is important to recognize the rarity of the case and the associated risks, both during pregnancy, after uterine emptying and in future pregnancies, and a follow-up after molar pregnancy is essential, which is interrupted approximately half of the patients. Adherence to follow-up is favored by the correct guidance to pregnant women, and prenatal diagnosis is fundamental for ensuring better doctor-patient dialogue. Therefore, it is important to highlight that, in order to properly manage hydatidiform mole pregnancies, due attention should be paid to the early diagnosis
