Endoscopic features of nodular lymphoid hyperplasia with red ring sign, due to hypervascularization at the base of the follicles, associated with granulocyte infiltrate.
Is colonic nodular lymphoid hyperplasia a marker of IBS?
Core tip: This study sheds light on colonic nodular lymphoid hyperplasia (NLH) in terms of prevalence, gender-distribution and association with known diseases. Our most relevant result is the identification of NLH as a putative marker of low-grade inflammation in a conspicuous subset of irritable bowel syndrome (IBS) cases.
