Although linear mucosal tears have been reported, we found a relatively rare case of wavy mucosal tear in collagenous colitis. This may be related to the mutual weak adhesiveness between the epithelium and collagen band. This complication necessitates great care to be taken while performing colonoscopy in patients suspected of collagenous colitis.
