Supernumerary nostril together with esophageal atresia, imperforate anus and patent ductus arteriosus: a case report and review of the literature.

Supernumerary nostril is an extremely rare congenital entity which results from aberrant embryological development. The review of the literature reveals that only 30 cases of supernumerary nostril have been reported. We report a rare case of supernumerary nostril in association with esophageal atresia, imperforate anus, and patent ductus arteriosus.
