Neonatal outcome of a giant placental chorioangioma in a late preterm newborn

ABSTRACT

Chorioangioma, the most common benign placental tumor, is found in 1% of placental pathology. Tumors greater than 4 cm are classified as giant and associated with multiple maternal and fetal complications. Authors are presenting a case report of a rare 16 cm giant chorioangioma, discovered at time of delivery, complicated with pregnancy induced hypertension and presenting with minimal fetal complication. This patient exhibited eventually a satisfactory perinatal outcome, complicated by severe anemia and thrombocytopenia requiring transfusion of blood products and bilateral, self-resolved spontaneous cephalohematomas. Chorioangiomas should be considered in the differential diagnosis of any newborn that presents with anemia.
