Collagenous colitis with mucosal tears on endoscopic insufflation: a unique presentation

Collagenous colitis with mucosal tears on endoscopic insufflation: a unique presentation.

Lansoprazole-associated collagenous colitis: unique presentation, similar to ischemic colitis.

soprazole-associated collagenous colitis manifesting some characteristic clinical findings: chronic diarrhea, typical endoscopic findings, pathological evidence of collagen bands, and rapid clinical improvement after discontinuation of lansoprazole. We have also often encountered patients taking lansoprazole presenting with chronic diarrhea and typical endoscopic findings. Although one publishe...

Acute Onset Collagenous Colitis with Unique Endoscopic Findings

We experienced a rare case of 72-year-old woman with acute onset collagenous colitis (CC) induced by lansoprazole. The patient developed acute abdominal pain, watery diarrhea, and melena that are quite rare in usual CC. We could find the characteristic colonoscopic findings such as active long liner ulcers in the patient. We also observed the healing courses of these unique findings. Our case i...

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...

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-...
