    en.wikipedia.org/wiki/Familial_adenomatous_polyposis

    Familial adenomatous polyposis (FAP) is an autosomal dominant inherited condition in which numerous adenomatous polyps form mainly in the epithelium of the large intestine. While these polyps start out benign , malignant transformation into colon cancer occurs when they are left untreated.

  3. Colorectal adenoma - Wikipedia

    en.wikipedia.org/wiki/Colorectal_adenoma

    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 .

    en.wikipedia.org/wiki/Colorectal_polyp

    Polyps are either pedunculated (attached to the intestinal wall by a stalk) or sessile (grow directly from the wall). [5] [6]: 1342 In addition to the gross appearance categorization, they are further divided by their histologic appearance as tubular adenoma which are tubular glands, villous adenoma which are long finger like projections on the surface, and tubulovillous adenoma which has ...

    en.wikipedia.org/wiki/Gardner's_syndrome

    Gardner syndrome can be identified based on oral findings, including multiple impacted and supernumerary teeth, multiple jaw osteomas that give a "cotton-wool" appearance to the jaws, as well as multiple odontomas, congenital hypertrophy of the retinal pigment epithelium (CHRPE), in addition to multiple adenomatous polyps of the colon. Gardner ...

    If adenomatous polyps are detected during this procedure, a colonoscopy is recommended. Medical societies recommend colonoscopies every ten years starting at age 50 as a necessary screening practice for colon cancer. [11] [21] The screening provides an accurate image of the intestine and also allows the removal of the polyp, if found. Once an ...

  7. Adenoma - Wikipedia

    en.wikipedia.org/wiki/Adenoma

    For example, adenomatous polyps in the colon may be pedunculated (lobular head with a long slender stalk) or sessile (broad base). The adenomatous proliferation is characterized by different degrees of cell dysplasia ( atypia or loss of normal differentiation of epithelium) irregular cells with hyperchromatic nuclei, stratified or ...

  8. Colorectal cancer - Wikipedia

    en.wikipedia.org/wiki/Colorectal_cancer

    The polyp to cancer progression sequence is the classical model of colorectal cancer pathogenesis. [57] In this adenoma-carcinoma sequence, [58] normal epithelial cells progress to dysplastic cells such as adenomas, and then to carcinoma, by a process of progressive genetic mutation. [59]

  9. Sessile serrated lesion - Wikipedia

    en.wikipedia.org/wiki/Sessile_serrated_lesion

    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]
