[Twin pregnancy with partial hydatidiform mole and alive fetus: case report]

We report a case of a pregnant patient with a twin of 29 gestational weeks, and partial hydatidiform mole with coexistent living fetus. She was admitted at gyneco-obstetric urgencies due to a mild preeclampsia that evolves to severe. She has a complicated vaginal delivery with obstetric bleeding and there was practiced a total abdominal hysterectomy. Newborn dies 30 days later due to secondary complications (extreme prematurity). Patient evolution was satisfactory and she is currently under follow-up therapy to gestational trophoblastic disease without clinical or biochemical evidence of persistence or recurrence.
