A colorectal polyp is a polyp (fleshy growth) occurring on the lining of the colon or rectum. [1] Untreated colorectal polyps can develop into colorectal cancer. [2] Colorectal polyps are often classified by their behaviour (i.e. benign vs. malignant) or cause (e.g. as a consequence of inflammatory bowel disease).
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. [1] [2] Usually, traditional serrated adenomas are found in the distal colon and are usually less than 10 mm in ...
Hyperplastic polyps on the right side of the colon do exhibit a malignant potential. ... with two lesions ≥10 mm >20 serrated lesions/polyps of any size distributed ...
Diagnosis requires colonoscopy, and is defined by the presence of either of two criteria: five or more serrated lesions/polyps proximal to the rectum (all ≥ 5 mm in size, with two lesions ≥10 mm), or more than 20 serrated lesions/polyps of any size distributed throughout the colon with five proximal to the rectum.

The colorectal adenoma is a benign glandular tumor of the colon and the rectum. It is a precursor lesion of the colorectal adenocarcinoma ( colon cancer ). [ 1 ] [ 2 ] [ 3 ] They often manifest as colorectal polyps .
The serrated polyposis syndrome (SPS) is a relatively rare condition characterized by multiple and/or large serrated polyps of the colon. Serrated polyps include SSLs, hyperplastic polyps, and traditional serrated adenomas. Diagnosis of this disease is made by the fulfillment of any of the World Health Organization's (WHO) clinical criteria. [4]
The other types of polyps that can occur in the colon are hyperplastic and inflammatory polyps, which are unlikely to develop into colorectal cancer. [ 15 ] About 5% of people aged 60 will have at least one adenomatous polyp of 1 cm diameter or greater. [ 16 ]
Polyps may be removed using cold biopsy forceps, cold snare polypectomy, hot biopsy forceps, hot snare polypectomy, endoscopic mucosal resection, or endoscopic submucosal dissection. Cold biopsy forceps may be used for small (diminutive) polyps 1-3 mm in size. [3]
