Localized giant inflammatory polyposis (filiform polyposis) with diverticula in ulcerative colitis

摘要

It is reported that approximately 10% to 20% of patients with ulcerative colitis (UC) and Crohn's disease have various kinds of polypoid lesions. Therefore, for the correct diagnosis, it is important to distinguish an inflammatory polyp from a pseudopolyp. We herein report a rare case of localized giant inflammatory polyposis (filiform polyposis) with multiple diverticula in UC.
