Traditional serrated adenoma is a premalignant type of polyp found in the colon, often in the distal colon (sigmoid, rectum). Traditional serrated adenomas are a type of serrated polyp, and may occur sporadically or as a part of serrated polyposis syndrome. Traditional serrated adenomas are relatively rare, accounting for less than 1% of all colon polyps. Usually, traditional serrated adenomas are found in the distal colon and are usually less than 10 mm in size.
