description: "Lymphoid nodular hyperplasia (LNH) of the terminal ileum and colon has been considered a mucosal response to nonspecific stimuli, most often infections, and consequently has been regarded as a pathophysiologic phenomenon during infancy and childhood. LNH can be ascertained by colonoscopy, whereby a lymphoid nodule is defined as an extruding follicle with a diameter of not more than 2 mm, and LNH is defined as a cluster of not more than 10 of such extruding lymphoid nodules (see Figure 1 of PMID:17368236)."
