Collagenous gastritis is a rare condition defined histologically by a superficial subepithelial collagen layer. This study further characterizes the morphologic spectrum of collagenous gastritis by evaluating a multi-institutional series of 40 patients (26 female and 14 male). The median age at onset was 16 years (range 3-89 years), including 24 patients (60%) under age 18. Twelve patients (30%) had associated celiac disease, collagenous sprue, or collagenous colitis. Hematoxylin and eosin slides were reviewed in biopsies from all patients and tenascin, gastrin, eotaxin, and IgG4/IgG immunohistochemical stains were applied to a subset...

Collagenous gastritis, a counterpart of collagenous colitis, is a rare disorder with less than 20 cases reported in the literature. A case of collagenous gastritis in a Japanese woman in her early 20s who had been receiving treatment for atopic dermatitis and bronchial asthma is reported. The patient complained of repeated epigastric pain, and endoscopy revealed multifocal atrophic areas and scars in the gastric body. Biopsy specimens showed a thickened eosinophilic band-like structure with entrapped capillaries approximately 30-70 micro m thick beneath the surface epithelium...
