Giant Filiform Polyposis not Associated with Inflammatory Bowel Disease: A Case Report

Filiform polyposis (FP) is an uncommon cause of non-neoplastic and non-syndromic polyposis. Several hypotheses concerning its pathogenesis have been published. FP is most frequently associated with a post-inflammatory reparative process; indeed, the most frequent association is with inflammatory bowel disease (IBD). FP is characterized by one to hundreds of uniform, slender, arborizing, vermiform projections of the large bowel mucosa and submucosa lined by normal or inflamed colonic mucosa. The most common sites for these polyps are the transverse and descending colon.
