Lin R, et al. - This study was performed to define the clinicopathological and colonoscopic characteristics in Chinese patients with ileal nodular lymphoid hyperplasia (NLH). In the biopsies, histology and immunohistochemical staining were performed. Ileocolonoscopic screening is an important step to find the NLH in terminal ileum patients with diarrhea, abdominal pain, hematochezia, and hypoproteinemia. Histological examination is vital for the exclusion of malignancy and chronic inflammation.
