Nodular lymphoid hyperplasia: A marker of low-grade inflammation in irritable bowel syndrome?

Figure 2 Endoscopic and histological features of nodular lymphoid hyperplasia. A-F: Three typical cases of nodular lymphoid hyperplasia (NLH), as observed at white light (WL) standard endoscopy (A-C) and narrow band imaging (NBI) endoscopy (D-F), respectively. NLH appear as slightly raised whitish areas, usually < 5 mm in diameter, closely spaced, difficult to recognize at WL, and easier to observe by NBI; G and H: Show the histological appearance of NLH (hematoxylin-eosin staining), as clusters of ≤ 10 lymphoid nodules, composed of hyperplastic benign lymphoid tissue.
