title: [Collagenous colitis. Morphologic and immunohistochemical study].
abstract: Collagenous colitis is a clinico-pathological entity characterized by chronic diarrhoeas and deposition of collagen beneath the epithelium surface of large bowel. We revised 265 endoscopy biopsy specimens of the large bowel from 198 consecutive patients with "aspecific chronic colitis". Morphometric study showed that were not significant differences among various tracts in the same patients regarding to the thickness of basament membrane. It was more than 11.9 +/- 0.49 mu only in 13 pts (6.6%), while it was 3.96 +/- 1.4 mu in the others. Immunohistochemistry study confirmed the normality of subepithelial basement membrane and the below deposition of the large quantity of collagen IV.
