Abstract
A 53-year-old woman with Hashimoto’s disease visited our clinic because of abnormality in the gastric barium examination. In blood biochemistry, IgE RAST of wheat was positive ; H. pylori IgG antibody and pepsinogen were classified into group D of the ABC screening method. Upper gastrointestinal endoscopy revealed chronic gastritis with reverse atrophy. Histopathological findings showed eosinophil infiltration of more than 20 / HPF in the gastric and duodenal mucosa, endocrine cell micronest with chromogranin A staining. Additionally, hyper gastrinemia and anti-parietal cell antibody, anti-intrinsic factor antibody were detected. Therefore, this case was diagnosed as type A gastritis accompanied by eosinophil infiltration in the gastric and duodenal mucosa Eosinophilic gastroenteritis and type A gastritis are still rare, but it is reported that type A gastritis is present in 25 % of group D of the ABC screening method, so type A gastritis is expected to increase by spread of the ABC screening method.
