A case of recurred gastric dysplasia associated with eosinophilic gastroenteritis / 대한내과학회지

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.
