[Collagenous enterocolitis. Apropos of a case and review of the literature].

Collagenous enterocolitis is a recent entity of which only two cases have been published. The authors report the association of collagenous colitis and collagenous sprue in a 67-year-old woman. The diagnosis of collagenous enterocolitis is based on the presence of a duodenal collagen deposit with partial villous atrophy associated with collagenous colitis.
