Although more commonly found higher in the large bowel on colonoscopy, rectal or anal polyps may also be seen on anoscopy or outside the anus. Anal polyps are the growth in the anal canal that must be removed for the biopsy. Further examination with colonoscopy is required for polyps confirmed to be adenomatous in order to check for proximal lesions in the rectum and colon since adenomatous polyps are precursors to cancer, and they must be distinguished from hyperplastic polyps, which are usually quite small (less than 5 mm) and have no neoplastic potential.
Hypertrophied Papillae is anal papilla at the dentate line, often confused with a polyp. Treatment is generally not indicated for confirmed hypertrophied papillae.
