    en.wikipedia.org/wiki/Sessile_serrated_lesion

    A sessile serrated lesion (SSL) is a premalignant flat (or sessile) lesion of the colon, predominantly seen in the cecum and ascending colon. SSLs are thought to lead to colorectal cancer through the (alternate) serrated pathway. [1] [2] This differs from most colorectal cancer, which arises from mutations starting with inactivation of the APC ...

    en.wikipedia.org/wiki/Serrated_polyposis_syndrome

    Sessile serrated polyps, as seen during endoscopy or colonoscopy, are flat (rather than raised) and are easily overlooked. Serrated lesions range in size from small (<5 mm) to large, and often have a "mucous cap" overlying the polyp. Serrated lesions are frequently located on the folds of the colon (haustral folds).

    en.wikipedia.org/wiki/Polyp_(medicine)

    Sessile polyps have a shorter pathway for migration of invasive cells from the tumor into submucosal and more distant structures, and they are also more difficult to remove and ascertain. Sessile polyps larger than 2 cm usually contain villous features, have a higher malignant potential, and tend to recur following colonoscopic polypectomy. [18]

    Micrograph of a sessile serrated adenoma. H&E stain. Sessile serrated adenomas are characterized by (1) basal dilation of the crypts, (2) basal crypt serration, (3) crypts that run horizontal to the basement membrane (horizontal crypts), and (4) crypt branching. The most common of these features is basal dilation of the crypts.

    en.wikipedia.org/wiki/Hyperplastic_polyp

    Serrated polyposis syndrome is a rare condition that has been defined by the World Health Organization as either: [3] ≥5 serrated lesions/polyps proximal to the rectum, all ≥ 5 mm in size, with two lesions ≥10 mm >20 serrated lesions/polyps of any size distributed throughout the large bowel with 5 proximal to the rectum.

  8. Colorectal polyp - Wikipedia

    en.wikipedia.org/wiki/Colorectal_polyp

    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).
