Two case stories of eosinophilic gastroenteritis are described. Both patients presented with chronic diarrhoea and weight loss. The first patient had eosinophilic infiltration predominantly in the mucosal layer of the intestine, and had in addition loss of protein in the stool. The other patient had predominantly subserosal eosinophilic infiltration and presented with eosinophilic ascites. Both patients were treated with prednisolone and responded immediately to therapy.
