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.

In agreement with our findings, these lymphocyte aggregates have been previously described in patients with IPF as "ectopic organized lymphoid structures," and have been shown to consist of nonproliferating, but activated CD3+ and CD20+ cells. 7 Mechanistic research from numerous laboratories has indicated that pulmonary lymphocytes may ...Serrated polyps are a class of colon polyps that have a serrated or saw-toothed appearance under a microscope.

As the name suggests, it is composed of normal lymphoid tissue, but devoid of sinuses. Benign lymphoid polyp is more common in children. Only excisional biopsy can diagnose this condition with certainty.Colon or rectal polyps. A polyp is a projection (growth) from the inner lining into the lumen (hollow center) of the colon or rectum. There are different types of polyps, which look different when seen with a microscope. Most polyps are benign (non-cancerous) growths, but cancer can start in some types of polyps.

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.
