Answer is A. This is a specimen of familial adenomatous polyposis with multiple polyps.Polyps are usually visible on sigmoidoscopy by the age of 15 years and will almost always be visible by the age of 30 years.Carcinoma of the large bowel develops 10-20 years after the onset of the polyposis.If over 100 adenomas are present at colonoscopy, the diagnosis can be made confidently.Ref: Bailey and love, 27e, page: 1260
