Polyps of the colorectum : Non-neoplastic and non-hamartomatous.

20:42 EDT 19th April 2014 | BioPortfolio

Summary of "Polyps of the colorectum : Non-neoplastic and non-hamartomatous."

Non-neoplastic and non-hamartomatous colorectal polyps or tumor-like lesions comprise a very heterogeneous group of changes in the colorectal mucosa or the colon wall. Mucosal prolapse-associated lesions and inflammatory polyps, which are predominantly associated with chronic inflammatory bowel disease, are the most prominent examples for polypoid lesions difficult to distinguish from neoplastic lesions such as adenomas, hyperplastic/serrated polyps/adenomas and invasive carcinomas. The considerably less frequent tumor-like lesions like heterotopias, endometriosis, amyloid tumors and pseudolipomatous changes are histologically often well defined and should be considered in the differential diagnosis of colorectal lesions. The etiology, endoscopic and histological appearance of these entities and their most important differential diagnoses are discussed.

Medical and Biotech [MESH] Definitions

The growth of INTESTINAL POLYPS. Growth processes include neoplastic (ADENOMA and CARCINOMA) and non-neoplastic (hyperplastic, mucosal, inflammatory, and other polyps).

Discrete tissue masses that protrude into the lumen of the COLON. These POLYPS are connected to the wall of the colon either by a stalk, pedunculus, or by a broad base.

Focal accumulations of EDEMA fluid in the NASAL MUCOSA accompanied by HYPERPLASIA of the associated submucosal connective tissue. Polyps may be NEOPLASMS, foci of INFLAMMATION, degenerative lesions, or malformations.

Discrete abnormal tissue masses that protrude into the lumen of the DIGESTIVE TRACT or the RESPIRATORY TRACT. Polyps can be spheroidal, hemispheroidal, or irregular mound-shaped structures attached to the MUCOUS MEMBRANE of the lumen wall either by a stalk, pedunculus, or by a broad base.

A well-differentiated, benign, hamartomatous proliferation of odontogenic epithelium, probably arising from the rests of Malassez.
