[Duplication of the anus and rectum in an adult. Report of 1 case].
It is reported a case of duplication of the anus and rectum. A 48 year old man, had two functioning rectae, one ending in its normal anatomical topography and the functioning but nor functional supernumerary rectum exteriorized in the left gluteal region trough a rudimentary anus. Histological studys demonstrated a rudimentary sphincter in the ectopic anus, and focal carcinamotous transformation of one of the four adenomatous polyps, encountered protruding through the normally located anus. The anal anomaly was associated with partial agenesis of the sacrum, absence of coccyx, sacral anterior meningomyelocele and hypoplasia of the twelve right rib. The frequency of the anomaly, its histology and embriology, as well as its classification within the malformations of the terminal gut, were revised in the medical bibliography. It is concluded that this type of anomaly has not been classified or describe, before.
