title: [Isolated and involvement in Crohn's disease (author's transl)].
abstract: Anorectal lesions in Crohn's disease are usually associated with colonic involvement. Under other circumstances, they reflect an additional localisation of the disease, being indicative of its progression. However, they may remain strictly isolated and pose a diagnostic problem. The authors report here a case of anoperineal lesions which remained isolated after a  5 year course of the disease and which led to the need for anoperineal excision.
