A Case of Collagenous Colitis


Collagenous colitis was first deacribed by Lindstrom(1976). This disorder is now a recognized disease of colon associated with chronic watery diarrhea which shows the typical histologic findings of a thickened subepithelial collagenous band. A few cases with such disease has been reported in this country. We have recently observed a 52-year-old businessman with chronic watery diarrhea without abdominal and intermittent mucobloody stool for several years. He has lost about 4 kg of his body weight for these 6 months period. Physical examination, laboratory and radiological studis were unremarkable. Colonoscopy disclosed no gross abnormalities through the entire colon including the terminal ileum but found the pronounced thiekening(about 10um) of intercryptal subepithelial collagen and chronic inflammation in the lamina propria in the histologic examination.
