Lymphoid aggregate polyp.

Lymphoid aggregates appear as slightly elevated nodules that may be normal in color or more red than the surrounding tissue. Sometimes they can look like small polyps. This is a harmless, non- cancerous condition. Lymphoid aggregates occur when the normal lymphoid tissue collects in a certain location. Submucosal lesions (lipomas, lymphoid aggregates, carcinoids, pneumatosis cystoides intestinalis) Adenomas and serrated polyps may be flat, sessile, or pedunculated (containing a stalk) Over 95% of cases of adenocarcinoma of the colon are believed to arise from these lesions The analysis assumes that polyps were either overestimated in size by 1mm (for example, a 10mm polyp is reclassified as 9mm) or underestimated (a 9mm polyp is reclassified as 10mm). Using these assumptions, the base prevalence of advanced neoplasia in 6–9mm polyps is 6.6%, with a range of 4.6–11.7%.Polyps are tumors that grow out of the mucous lining inside your hollow organs, like your gastrointestinal tract, your nose or female reproductive organs.

Abstract. Colonic mucosa-associated lymphoid tissue (MALT) lymphomas are rare and a definitive treatment has not been established. Solitary or multiple, elevated or polypoid lesions are the usual appearances of MALT lymphoma in the colon and sometimes the surface may reveal abnormal vascularity.

A tubular adenoma is a type of polyp found in the large intestine which includes the colon and rectum. It starts from glandular cells that cover the inside surface of the large intestine. Tubular adenomas are considered precancerous conditions because, while most are benign (non-cancerous), they have the potential to develop into colorectal cancer called adenocarcinoma over time if left untreated.

Colonic polyps - These are outgrowth of tissue from the lining of the colon. There are two kinds of polyps: Benign - These do not become cancerous and include "hyperplastic" and "inflammatory" polyps that usually require no treatment. Neoplastic - These include adenocarcinoma (colon cancer) and adenomas, which are precancerous.

In addition, multiple lymphoid aggregates are newly formed in the submucosa (submucosal lymphoid aggregate (SLA)) and deeper.

A lymphoid polyp of the rectum is a benign submucosal tumor-like growth associated with localized hyperplasia of lymphoid follicles in the submucosa.
