May 1, 2013 · Lymphoid aggregates appear as slightly elevated nodules that may be normal in color or more erythematous than the surrounding tissue, which may prompt biopsy and earlier follow-up colonoscopy based on total numbers of polyps. 19 In our study, this discordant recommendation may also have reflected the timing of the reports, because endoscopists ... In addition, multiple lymphoid aggregates are newly formed in the submucosa (submucosal lymphoid aggregate (SLA)) and deeper. The aim of the present study was to investigate the cellular immune ...Core tip: Mucosa-associated lymphoid tissue (MALT) lymphoma in the large intestine is a rare disease, but it is a clinically important condition that requires proper evaluation. Most of the colonic MALT lymphomas mainly present as a protruding and/or ulcerative lesion, and rarely present as a flat lesion. It is not easy to detect MALT lymphoma of the flat type and could be misdiagnosed.Nodular lymphoid aggregates were also seen (Figure 1B).

A lymphoid polyp is an often benign, focal proliferation of gut associated lymphoid follicles. Lymphoid polyps are rarely found in adults and are usually found in terminal ileum or rectum. These polyps are usually asymptomatic though possible association with development of malignant lymphoma has been described.Always consider MCL in biopsies of polyps with large lymphoid aggregate ˚ Look for monotonous population of cells ˚ Angulated nuclear contours and pink histiocytes may be helpful • Aggressive variants (blastoid, pleomorphic) must be recognized and reported • Beware of misdiagnosing blastoid or pleomorphic variants of MCL as DLBCL ˚Around 75% of colorectal cancers start from adenomatous polyps, and about 80% of all colon polyps are adenomas. But only about 5% of adenomas are actually malignant . The risk of a random, average-size colon polyp becoming cancerous is estimated to be 8% over 10 years and 24% over 20 years.

Benign lymphoid polyps of the rectum, also termed "Rectal tonsil" or "Pseudolymphoma," are submucosal tumor-like growths with localized hyperplasia of the lymphoid follicles and are often discovered incidentally during colonoscopy.

They affect about 20% to 30% of American adults. Polyps are abnormal growths that start in the inner lining of the colon or rectum. Some polyps are flat while others have a stalk.BACKGROUND AND AIMS—A histopathological feature considered indicative of ulcerative colitis (UC) is the so-called basal lymphoid aggregates.Their relevance in the pathogenesis of UC is, however, unknown. We have performed a comprehensive analysis of the immune cells in these aggregates most likely corresponding to the lymphoid follicular hyperplasia also described in other colitides.Other pathologic conditions identified included hyperplastic polyps (16%), lymphoid aggregates (3.5%), and invasive adenocarcinoma (0.1%). Overall, follow-up recommendations correlated with established guidelines in 97% of cases.

It is not meant to be comprehensive and should be used as a tool to help the user understand and/or assess potential diagnostic and treatment options.When a lymphoid population is identified on colon biopsy, lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) must be excluded, 58 and immunohistochemical stains are helpful in this regard. The CD20-positive B-cells should not co-express CD43 in reactive lymphoid polyps, and the co-expression would indicate MALT lymphoma. N2 - Lymphoglandular complexes (LGCs) are lymphoid nodules containing intestinal mucosa, present in close apposition to muscularis mucosae or submucosa.

Abstract. Lymphoglandular complexes (LGCs) are lymphoid nodules containing intestinal mucosa, present in close apposition to muscularis mucosae or submucosa. Rarely, colorectal adenomas involve submucosal LGCs, simulating invasive adenocarcinoma with associated submucosal lymphoid aggregates, and presenting a diagnostic pitfall.Lymphoid follicles are a normal component of gut-associated lymphatic tissue. They are aggregates of lymphocytes surrounding germinal centers that straddle the muscularis mucosae. ...
