title: Eosinophilic gastroenteritis associated with multiple gastric cancer.
abstract: Eosinophilic gastroenteritis (EG) is an inflammation of the digestive tract that is characterized by eosinophilic infiltration. There are no specific symptoms, and are related to the layer in which eosinophilic infiltration is observed. A 69-year-old Japanese man presented to our hospital with a history of general malaise, diarrhea, and dysgeusia. Esophagogastroduodenoscopy showed reddish elevated lesions that were edematous all over the gastric mucosa. In addition, three tumors were also observed. The biopsies of the reddish elevated mucosa revealed eosinophilic infiltration and tubular adenocarcinoma from the tumors. Colonoscopy showed abnormal reddish elevated mucosa. The biopsies from the reddish elevated mucosa showed eosinophilic infiltration. From the abdominal contrast computed tomography scan, tumor stain was seen in the anterior wall of the gastric body. No ascites, intestinal wall thickening, or lymph node swelling were found. A slight elevation in the serum immunoglobulin E (IgE), 480 IU/ml, was found from the laboratory test results; other laboratory results were within normal limits including the number of peripheral eosinophils. No specific allergen was found from the multiple antigen simultaneous test and from the skin patch test. The parasitic immunodiagnosis was negative. He was diagnosed with EG associated with gastric cancer and underwent total gastrectomy, regional lymph node dissection with reconstruction by a Roux-en-Y method. He was prescribed prednisolone after the operation and showed a good clinical response. There are many case reports on EG, but none of them were associated with cancer. We encountered a case of EG associated with multiple gastric cancer; the patient underwent total gastrectomy.
