Lymphoid aggregate polyp.

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 ...Visualization and removal of precancerous polyps are essential goals of screening colonoscopy, although detection of polyps over poorly visualized areas such as appendix can be challenging. Endoscopic recognition of appendiceal lesions is limited to the base of the cecum and appendiceal orifice. The appendiceal orifice is described in endoscopy ...Ileocecal valve. Drawing of the ileocecal valve (Gray's anatomy). The ileocecal valve, abbreviated IC valve, is the divider between the small bowel and cecum. It is seen by pathologist in some subtotal colectomies (e.g. right hemicoloectomies) and occasionally biopsied.Colon biopsies, and colon polyps in particular, are among the most frequently examined specimens by pathologists. The 2012 Survey of Endoscopic Capacity performed by the Centers of Disease Control and Prevention estimated that 15 million colonoscopies are performed annually. 1 Many different lesions, neoplastic (ie, adenoma) and non-neoplastic (ie, lymphoid aggregate), can account for a ...

The surgical specimen revealed multiple, large, tree-like branching polypoid masses, with elongated or pedunculated stalks or a wide broad base, measuring up to 14.0×5.0×4.5 cm in dimensions of the largest polypoid mass (Fig. 2A).Upon microscopic examination of the lesions, most of the polyps had long, elongated, and loose or fibrotic submucosal elongated stalks, while some were sessile.On pathology examination, the villiform polyp from the sigmoid colon was identified as a CMSEP. The polyp was lined by normal-appearing colonic mucosa, and the underlying submucosa contained increased blood vessels and inconspicuous lymphatic channels (detected on immunohistochemistry stain for D2-40), without significant inflammation in the lamina propria (Figure (Figure2). 2).In the colon, lymphoid tissue occurs mainly as isolated lymphoid follicles that are composed mainly of B lymphocytes. 1,2 Such gastrointestinal tract MALT plays an important role in immune ... et al: A case of mucosa-associated lymphoid tissue lymphoma of the sigmoid colon presenting as a semipedunculated polyp.

Citation, DOI, disclosures and article data. Gastrointestinal nodular lymphoid hyperplasia is a type of nodular lymphoid hyperplasia that can be found elsewhere in the body. It is formed out of gut-associated lymphoid tissue (GALT), and most often is a diagnostic dilemma for radiologists in the stomach and terminal ileum.Of the diminutive polyps, 40.7% were adenomatous, 37.2% were hyperplastic, 17.9% were mucosal tags or lymphoid aggregates, and 4.3% were mixed; 0.26% contained atypia, and none were cancerous. In the right colon and transverse colon, diminutive polyps were more likely to be neoplastic (p < 0.0001), but in the left colon they were more likely to ...

The sessile serrated polyp (SSP), also known as sessile serrated adenoma, is the evil twin among the colorectal cancer precursors.

Regulatory T cells seem to play a central role in maintaining immune tolerance in the gut mucosa. Previously we have shown that interleukin (IL)-10 is produced at high levels in the inflamed colonic tissue of ulcerative colitis (UC) patients. The cellular source was CD4 + T cells, suggesting local activation of regulatory T cells.Abstract.

The CD20-positive B-cells should not co-express CD43 in reactive lymphoid polyps, and the co-expression would indicate MALT lymphoma.Background: Ectopic lymphoid tissues (eLTs) and associated follicular helper T (T FH) cells contribute to local immunoglobulin hyperproduction in nasal polyps (NPs).Follicular regulatory T (T FR) cells in secondary lymphoid organs counteract T FH cells and suppress immunoglobulin production; however, the presence and function of T FR cells in eLTs in peripheral diseased tissues remain poorly ...Results.
