Lymphoid aggregate polyp
Lymphoid aggregates (LA) develop during the proliferative phase of the menstrual cycle in the human uterine endometrium (EM). They contain mostly CD8+ T cells and B cells. As these LA are absent immediately following menses, they may arise by division of cells resident in the EM, or by division of a limited number of precursor cells that ...However, having any serrated polyp ≥ 10mm in size was associated with increased risk for large serrated polyp (≥10mm SSP, TSA, or HP), ranging from an absolute risk of 12.3% (8/65) for no concurrent conventional adenoma to 11.2 % (2/18) for concurrent high risk adenoma, compared to an absolute risk of 0.7% (18/2,396) for those without ...

Lymphoid aggregates were present adjacent to foci of misplaced epithelium in 37% of cases. Fresh hemorrhage ...Introduction. Mucosa-associated lymphoid tissue (MALT) lymphoma, which is also referred to as extranodal marginal zone lymphoma, is a form of non-Hodgkin lymphoma (NHL) that predominantly involves the gastrointestinal tract [1,2].]. The stomach is the most commonly affected site with MALT lymphoma [].The involvement of colon is very rare, and the presentation can vary from incidental finding ...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.One of the classic histologic elements of lymphangioma (which reliably distinguishes it from other cystic neoplasms in the abdomen, including hemangioma and mesothelial cysts) is dense lymphoid aggregates. 1 While most of the pediatric lymphangiomas exhibited this pattern, it was present in only a minority of adult lymphangiomas. These findings ...We report here three cases of benign lymphoid hyperplasia of the rectum associated with prominent marginal zone hyperplasia, which caused serious difficulty in the differential diagnosis from the polypoid type of mucosa-associated lymphoid tissue (MALT) lymphoma. Colonoscopy demonstrated small sessile polyps in all three cases.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.We report a case series of histologic LC pattern of injury (LCPI), presenting as endoscopic polyps, and compare them with typical LC cases. Eighteen archived (2009-2019) polypoid LCPI cases without an associated cause of polyp, such as adenoma, hyperplastic change, or lymphoid aggregate, were retrieved from 17 (12 female and 5 male) patients.Primary histology of the polyp revealed lymphoid aggregates compatible with a lymphoid polyp.

Adenomatous colon polyps are thought to progress histologically from adenoma to dysplasia, to carcinoma; thus screening detection of precancerous polyps is considered useful.

Colon polyps are usually asymptomatic but may ulcerate and bleed, cause tenesmus if in the rectum, and, when very large, produce intestinal obstruction. Colonic polyps may be neoplastic (eg, adenomas) or non-neoplastic (eg, inflammatory polyps).In localized lymphoid hyperplasia of the large intestine, endoscopic lesions are either submucosal tumors or polyps . Diffuse lymphoid hyperplasia is common and benign; it is thought to be a general response of mucosal lymphoid aggregates in the small and large intestine to an unknown stimulus [ 2 ].
