Background/Aim Lymphoid follicles hyperplasia (LH) is sometimes observed in the normal colon as small, round, yellowish-white nodules. LH is associated with food hypersensitivity and bowel symptoms and histologically characterized as intense infiltration of lymphocytes or plasmacytes. It is suggested that LH represents inflammatory immune response in the colonic mucosa.

Cecal polyps involving the appendiceal orifice (AO) present a unique therapeutic challenge because they are difficult to evaluate and subsequent endoscopic resection has an increased risk for incomplete removal and complications.

Lymphoglandular complexes (LGCs) are lymphoid nodules containing intestinal mucosa, present in close apposition to muscularis mucosae or submucosa.
