The association of malignant tumors and peripheral eosinophilia or tissue eosinophilic infiltration has been uncommonly described. Moreover, a recent study has demonstrated some gastric cancers can express eosinophilic chemotactic factor. Interestingly, we recently experienced a case of recurrent eosinophilic gastroenteritis with relapsing gastric dysplasia. It is suggested that gastric dysplasia can also produce eosinophilic chemotactic factors and eosinophilic gastroenteritis can develop with recurred dysplasia. In this patient, eosinophilia served as an indicator of disease activity or as a marker. Eosinophilia may represent an important disease marker with prognostic significance and may rarely cause disease on its own.

We report a case of gastric adenoma which was found incidentally on 18F-FDG PET/CT study for cancer screening in asymptomatic patient. It showed focal and intensely increased FDG uptake in the antrum of stomach. On the gastroduodenoscopy, it showed flat elevated lesion with irregular margin. Histologically, the lesion was confirmed gastric adenoma with high grade dysplasia and removed by endoscopic mucosal resection.
