Chorangioma is a placental lesion consisting of capillary proliferation in chorionic villi and typically presents as a nodule or as multiple nodules on the placenta. It is a rare abnormality of placental vascular development and its clinical characteristics depend on size of the lesion. Giant chorangioma is chorangioma with an average diameter greater than 5cm. It is associated with both maternal and foetal complications. This report documents our findings in a hysterectomy specimen removed from a 40-year old female, following emergency hysterectomy for intractable postpartum haemorrhage after an elective caesarean section for three previous sections. A giant chorangioma was discovered in association with both placenta praevia and placenta increta. The outcomes for both mother and child were good.
