[Giant hemangioma of the placenta as a cause of life-threatening anemia in the newborn infant with hydrops congenitum].

A premature infant (33.-34. gestational week) delivered by caesarean section suffered from congenital hydrops and severe anaemia (7,2 g/dl) with pronounced marks of erythroblastosis; its placenta contained a haemangioma of 750 gs. A gigant haemangioma is extremely rare and can lead to a characteristic symptom complex endangering the life of mother and foetus.
