Huge placental myxoid chorangioma presenting with severe antepartum hemorrhage

Abstract

A 2nd gravida presented at 27 weeks with antepartum hemorrhage. Ultrasound showed a single live fetus (parameters ~23 weeks) and a huge placenta with multiple cystic areas extending into the lower uterine segment; some of which showed increased vascularity on colored doppler. A diagnosis of low lying placenta with a possibility of chorangioma or a partial mole was made. The next bout of antepartum hemorrhage was severe necessitating an emergency cesarean. Histopathology of the placenta (weighing 2240 grams) revealed a myxoid chorangioma. All features in this woman are uncommonly reported in literature (large size, myxoid degeneration and severe antepartum hemorrhage necessitating a cesarean). Key Words: Placental Chorangioma; Placental Chorioangioma, Antepartum Hemorrhage, Myxoid.
