Mucosal Tears Can Occur Spontaneously in Collagenous Colitis

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-...

Endoscopic Manifestations and Mucosal Patterns Associated to Collagenous Colitis

Microscopic colitis (MC) are clinical pathologic entities characterized by secretory-like aqueous chronic diarrhea, in its large majority without hematochezia. From the first descriptions of MC1, normal endoscopic and radiological findings have been a pathognomonic feature. It is thought that up to 20% of adults with chronic diarrhea who have an endoscopically normal colonoscopy may have MC. Mo...
