Five infants with sacral hemangiomas and a particular constellation of congenital abnormalities are described. Three of the five infants had an imperforate anus associated with a fistula. Three of the five had renal anomalies; four had bony abnormalities of the sacrum, and three of these also had a lipomeningomyelocele. Four had skin tags, three of which were in the genital and sacral areas. Two of the five also had abnormalities of the external genitalia. This constellation of defects associated with a sacral hemangioma has not been, to our knowledge, elaborated previously.
