[Segmental tuberculosis of the colon manifested by rectal stenosis].

Colonic tuberculosis is currently exceptionally rare in western countries. This interesting report reminds of its existence and emphasizes the diagnostic problems with Crohn's disease in the past. The barium enema enables to show the main aspects of colonic tuberculosis, i.e. variable forms of stenosis. The contribution of colonoscopy is essential in defining the lesions and allowing multiple biopsies. These biopsies may show the presence of granulomas with caseous necrosis, and possibly the Koch Bacillus on direct examination or in culture. The conditions of prescription of the medical treatment are similar to that of other tuberculous locations. Surgery is indicated in the presence of complications, when there is a doubt the malignant nature of the lesion, finally at the stage of cicatricial stenosis.
