Filiform polyposis of the colon presenting as massive hemorrhage: an uncommon complication of Crohn's disease.

A case of localized filiform polyposis of the colon is presented. This lesion was part of a more generalized inflammatory bowel disease with clinicopathological features indicative of Crohn's disease. An unusual feature of this case was profuse rectal bleeding, initially from a solitary sigmoid ulcer and later from the area of filiform polyposis. A step by step clinicopathological follow-up emphasizing the development of filiform polyps is provided.
