Lymphoid aggregate polyp.

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.Prominent lymphoid aggregate. dx15.

Lymphoid polyps (present in 15% of patients) are hyperplastic submucosal lymphoid aggregates, most likely due to a nonspecific infection (exposure to bacteria and viruses). Submucosal lymphoid tissue is prominent in children, particularly in the distal ileum (Peyer patches).Peyer's patches (PPs) refer to organized lymphoid aggregates located within both the small and large intestines of many mammalian species (Liebler-Tenorio and Pabst, 2006). Isolated lymphoid follicles may also be abundant throughout both the small and large intestines of some species, including mice and humans ( Moghaddami et al., 1998 ; O ...I had biopsy come back as colonic mucosa with prominent lymphoid aggregate.
