Gestação gemelar com mola hidatiforme completa e feto vivo

Twin pregnancy with complete hydatidiform mole coexisting with a live fetus is a rare entity, and although the recommendations are expectant management of various maternal and fetal complications are described, such as increasing the number of spontaneous abortion, premature delivery, vaginal bleeding, pre‐eclampsia and severe persistent trophoblastic disease, among other complications. In this paper, we describe the clinical course of a case of GGMC who developed thyrotoxic crisis, preeclampsia severe, termination of pregnancy and maternal need for intensive care. Fetal autopsy showed a female fetus with no apparent defects; with placental changes favoring chromosomal disorders. The evaluation of ovular remains showed villi with trophoblastic hyperplasia and vesicles, suggestive of complete mole. Currently, after 15 months of follow up, the patient remains asymptomatic with undetectable levels of chorionic gonadotropin.
