Collagenous colitis with unique colonoscopic findings.

temic lupus erythematosus (SLE) pre− sented with chronic watery diarrhea, which began 8 months after SLE diagno− sis. She was given oral medications such as loperamide but they were unsuccess− ful. Finally she was admitted for evalua− tion of the chronic diarrhea, which was then of 4 months’ duration.

Mucosal tears and colonic perforation in a patient with collagenous colitis.

Collagenous colitis, which is clinically characterized by chronic non-bloody diarrhea, is a variant of microscopic colitis. It can be diagnosed on histological grounds, with thickening of the subepithelial collagen layer [1–3]. The colonic mucosa is usually endoscopically normal, although minor abnormalities such as edema or erythema can be seen [2,3]. Serious complications are rare. A 69-year-...

of bloody diarrhea. Except for partial gastroduodenectomy because of a duodenal ulcer, the subject was healthy and was not taking any regular medication. He had not recently visited any foreign countries. Physical examination was unremarkable. Routine laboratory tests and complete blood analysis were normal.

Linear mucosal defects: a characteristic endoscopic finding of lansoprazole-associated collagenous colitis.

copathologic entity characterized by chronic watery diarrhea and, histologically, by the subepithelial deposition of collagen [1,2]. Some luminal antigens, including nonsteroidal anti-inflammatory drugs (NSAIDs) and proton pump inhibitors (PPIs), particularly lansoprazole, are thought to contribute to the development of collagenous colitis. On endoscopy, collagenous colitis usually shows no orm...
