For the purposes of this review we divide the discussion into; 1. ‘true’ anal polyps, that is, lesions that essentially always present as a discrete elevated lesion, and 2. ‘polypoid’ anal lesions, that is, lesions that can present as a polyp or polyp-like mass in some patients Author: Mark Bettington, Ian Brown.
The likelihood of cancer in an adenomatous polyp at the time of discovery is related to size, histologic type, and degree of dysplasia; a 1.5-cm tubular adenoma has a 2% risk of containing a cancer vs a 35% risk in 3-cm villous adenomas. Serrated adenomas, a somewhat more aggressive type of adenoma, may develop from hyperplastic polyps. This causes a specific type of polyp, serrated adenomatous polyps, to grow in the upper part of the colon. They can turn into colon cancer. They can remove most polyps as the polyps are found.
Villous Adenoma found in my Anal Canal at the Verge and Mid-Rectum. just over 2 cm in a polyp sort of shape like yours (only larger).
