Chorioangiomas are the most common benign tumors of the placenta. The pathologist is able to recognize these tumors in 1% of all examined specimens, but 80% of them are small and of no clinical significance. The larger chorioangiomas are very rare and often associated with complications such as placental abruption, fetal anemia, premature labor and preterm delivery. Early diagnosis of such a large placental tumor is necessary for the obstetrician to adjust the management of pregnancy to reduce fetal and maternal mortality and morbidity. We present a case of multiple placental chorioangiomas, in which the largest was 8 cm in diameter, detected in the 33rd week of pregnancy and associated with polyhydramnion and fetal anemia because of fetomaternal transfusion. Early diagnosis and well-timed delivery avoided severe complications for mother and neonate.
