Chorioangioma is the most frequent non trophoblastic tumour of the placenta with a incidence ranging from 0.01 to 1.3%of placentas examined. Lesions larger than 5 cm may cause foetal and maternal complications. We report a case of a large chorioangioma of the placenta associated with diffuse haemangiomatosis in a newborn female. The relationship between placental chorioangioma and haemangioma is discussed.
