Core tip: The diagnosis of collagenous gastritis is based on the histological findings of collagen bands thicker than 10 μm in the subepithelial layer and infiltration of inflammatory mononuclear cells in the lamina propria. Similar histological changes are seen in the colon in collagenous colitis. While there are many cases of collagenous colitis published in the literature, there are only 60 reported cases of collagenous gastritis since the disease was first identified in 1989. The present review discusses the characteristics of this disease entity and summarizes the cases reported to date. Better knowledge and understanding of collagenous gastritis will help physicians to diagnose the disease, and the accumulation of future cases will help to develop a standard therapeutic strategy.
