Eosinophilic esophagitis is characterized by symptoms of esophageal dysfunction 
and eosinophil-predominant esophageal inflammation. Eosinophilic inflammation in 
other parts of the gastrointestinal tract is absent and several differential 
diagnoses for esophageal eosinophilia have to be excluded before diagnosing 
eosinophilic esophagitis. Most patients are male and have concomitant atopic 
disorders. Therapeutic options are based on drugs, diet and dilation.
