[Collagenous enterocolitis. Apropos of a case and review of the literature]. / L'entérocolite collagène. A propos d'une observation avec revue de la littérature.

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. The symptom appeared one month after non-steroidal antiinflammatory treatment. The authors discuss the role of drug toxicity in the pathogenesis of collagenous enterocolitis.
