[Alkaptonuria and ochronosis: presentation of a clinical case].

In the present work a case of alcaptonuric arthropathy is described. The rareness of such type of pathology has suggested us a re-examination of the ptrtaining literature; after a necessary introduction concerning the etiopathogenetic and anatomo-pathological part, we detailedly explain the clinico-diagnostical aspect. We subsequently document the case we had the opportunity to observe. Due to the seriousness of the articular involvement, we subjected it to radical surgical treatment, from which it enjoyed a real advantage.
