  Fig. 1. (A) On conventional endoscopy, multiple, reddish, nodular lesions with variable sizes are seen in the background of atrophic gastritis in the gastric body and fundus. (B) Magnifying endoscopy with narrow-band imaging (ME-NBI) of the reddish nodular lesions reveals small, round pits surrounded by honeycomb-type subepithelial capillary networks (SECNs) with a regular arrangement of collecting venules. (C) ME-NBI of the surrounding atrophic mucosa reveals loss of the normal SECNs and round pits, with an irregular arrangement of the collecting venules. (D) Endoscopic biopsy of the reddish nodular lesions reveals intact oxyntic mucosa without evidence of atrophy or intestinal metaplasia, and pseudohypertrophy of parietal cells with protrusion into the gland lumen (hematoxylin and eosin stain, ×200).
