 We reported the case of a young Japanese woman with collagenous gastritis. A 23-year-old female was refered to our institution with a complaint of epigastric pain. Endoscopic examination disclosed a depressed area without erosion in the gastric body. High-resolution magnification endoscopy with narrow-band imaging demonstrated loss of normal subepithelial capillary network and round pits, with irregular arrangement of collecting venules, whose findings corresponded to those of gastric atrophy, in the depression. Biopsy specimens revealed a thickened eosinophilic band-like structure, which was positive on Azan staining but negative on amyloid staining, beneath the surface epithelium. It was accompanied by infiltration of inflammatory cells in the lamina propria. Little is known about the natural history and pathogenesis and further case studies are warranted to clarify the nature of this rare entity.
