Abstract:A 32‐year‐old female was admitted to Osaka National Hospital for remarkable anemia. She had a history of food allergy for the past 6 years. Laboratory examinations revealed remarkable iron de?ciency anemia and protein‐losing gastroenteropathy. On upper gastrointestinal endoscopy, multiple nodular lesions resembling verrucous gastritis were observed in the gastric antrum and the duodenal bulb. Marked mucosal eosinophilic in?ltration was seen in the biopsy specimens. Small intestine and colon were normal by X‐ray examination and colonoscopy, respectively. She was diagnosed as eosinophilic gastritis. Her symptoms, laboratory data and endoscopic ?ndings improved by regulation of food intake and administration of steroid. Rare endoscopic appearance of eosinophilic gastritis probably has strong correlation with food allergy.
Keywords:eosinophilic gastritis  food allergy  protein‐losing gastroenteropathy
