RESUMO
@#Sad fetus syndrome is a rare gestational trophoblastic disease wherein a hydatidiform mole coexists with a live fetus. We report a case of a 40‑year‑old G4P2 (2012) with 29 weeks gestational age who came in with vaginal bleeding and labor pains. A previous ultrasound done at 16 weeks of gestation showed a live fetus, a normal placenta, and a focal multicystic uterine mass. The beta‑human chorionic gonadotropin level was 1,500,000 mIU/mL. She delivered a live preterm female fetus weighing 900 g by partial breech extraction. The placenta was grossly normal. Postpartum hemorrhage secondary to uterine atony was encountered and a total hysterectomy with bilateral salpingectomy was performed. Cut section of the specimen revealed molar tissue at the anterofundal area with evidence of gross myometrial invasion. The histopathologic finding was consistent with a diagnosis of partial hydatidiform mole. This paper describes the incidence, pathology, clinical presentation, diagnosis, treatment, and postpartum course of this rare condition.
