Eosinophilic Esophagitis is infiltration of esophagus mucosa by eosinophil leucocyte. It is rarely observed in children and the symptoms are similar to gastroesophageal reflux. This case, which was applied esophagus balloon dilatation in the pediatric surgery due to dysphagia and diagnosed eosinophilic esophagitis, was presented in order to attract attention to the approach to the child with dysphagia. Total IgE= 834 IU/mL and specific IgE (-), Fx5 (-) was found negative. In the upper GIS endoscopy, it was observed that esophagus mucosa was pale, its structure was hard and its motility was disordered and a couple milimetric white lesions were observed as well. In the esophagus biopsy materials, it was observed that the eosinophil infiltration in the mucosa was 60%. With the diagnosis of Eosinophilic Esophagitis, the case was started on oral prednisolone 1 mg/kg/day. In the polyclinic control of the case after a week, it was observed that there was a significant decrease in the complaints about dysphagia and in the one-month control the complaints were all gone. In the symptoms similar to dysphagia and reflux, especially if the case is not responding to gastroesophageal reflux treatment, the diagnosis of Eosinophilic Esophagitis should absolutely be considered.
