Filiform polyposis or giant inflammatory polyp is an uncommon benign lesion that has principally been reported in patients with evidence of inflammatory bowel disease, Crohn's disease or ulcerative colitis. It appears to be a sequella of diffuse mucosal inflammation. More rarely, PF found in association with colonic non specific inflammation. PF has rarely been reported in patients without previous colonic disease. We report the case of a 60-year-old woman without history of colonic disease who presented a PF revealed by hematochesia.
