  2. Sessile serrated lesion - Wikipedia

    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 ...

  3. Sessility (motility) - Wikipedia

    en.wikipedia.org/wiki/Sessility_(motility)

    Blue mussels, Mytilus edulis, are sessile and exhibit clumping. Clumping is a behavior in sessile organisms in which individuals of a particular species group closely to one another for beneficial purposes, as can be seen in coral reefs and cochineal populations. This allows for faster reproduction and better protection from predators.

  4. Serrated polyposis syndrome - Wikipedia

    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).

    Tubular adenomas (tube-like shape) are the most common of the adenomatous polyps; they may occur everywhere in the colon and they are the least likely colon polyps to develop into colon cancer; Tubulovillous; Villous adenomas are commonly found in the rectal area and they are normally larger in size than the other two types of adenomas.

  6. Colorectal adenoma - Wikipedia

    en.wikipedia.org/wiki/Colorectal_adenoma

    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.

  7. Traditional serrated adenoma - Wikipedia

    en.wikipedia.org/wiki/Traditional_serrated_adenoma

    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 ...

  9. Clostridioides difficile - Wikipedia

    en.wikipedia.org/wiki/Clostridioides_difficile

    C. difficile secretes mucolytic enzymes like CWp84 to degrade the colonic mucosa. These spores are also capable of adhering to colon cells. Additionally, C. difficile is a motile bacterium that can switch between both the motile and sessile phases, a process regulated by cyclic-di-GMP.
