A case of ectopic anus localized on the right gluteus

Abstract

A case of a gluteus-localized ectopic anus on the right side is described. A P-month-old boy had a severe sacral anomaly with atrophy of the right lower extremity and a pes equinus deformity. Transcutaneous muscle stimulation showed a well-developed muscle complex, and parasagittal muscle fibers have been localized obliquely. Although he has severe sacral anomalies, the posterior sagittal anorectoplasty procedure could be performed. This unique case provides a good demonstration of not only the ectopically localized anus but also the ectopically localized muscle complex. Copyright (C) 1996 by W.B. Saunders Company
