title: [A Case of Eosinophilic Enteritis Needed to Distinguish from a Tumor of the Small Intestine].
abstract: A 75-year-old woman was diagnosed with aplastic anemia 6 months ago and was under follow-up at our hospital. She had originallypresented to our hospital because of ongoing diarrhea and abdominal pain. Her blood tests showed a rise in inflammatorymarkers (WBC count was 6,900/mL[eosinophil was 1.3%]and CRP was 8.60mg/dL). Her abdominal computed tomography(CT)scan showed gastric wall and small intestine edema as well as ascites. There was no evidence of free air. We diagnosed her with generalized peritonitis and performed an emergencyoperation . Intra-operatively, moderate amounts of yellowish ascitic fluid were noted, as was a diffuse reddening of the small intestine. We performed a partial resection of the small intestine. Histopathological examination showed transmural infiltration of inflammatorycells mainly comprising eosinophilic leukocytes. Eosinophils were also present in the ascitic fluid. Post-operative blood tests confirmed eosinophilic, and we diagnosed her with eosinophilic enteritis. She was started on corticosteroids and her symptoms improved immediately. We report a rare case of eosinophilic enteritis with a review of the pertinent literature.
