Omphalocele, colonic atresia, and Hirschsprung's disease: an unusual cluster of malformations in a single patient.

Omphalocele, colonic atresia (CA), and Hirschsprung's disease (HD) are individually rare congenital malformations. An association between CA and HD has been described, but the co-occurrence of all three malformations has not been previously reported. We present an infant born with all three malformations and review the management issues relevant to this case, with an emphasis on the importance of considering co-existent HD in any infant born with CA.
