N2 - 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. However, in contrast to IBD where the biopsy usually shows basal plasmacytosis and basal lymphoid aggregates, the lymphoplasmacytic inflammatory infiltrate in microscopic colitis is typically localized to the upper half of the mucosa, and there is usually prominent intraepithelial lymphocytosis. ...
