The main diagnostic methods of EoE are endoscopy (small, whitish, dotted or linear exudates, mucosal edema, mucous membranes, fine concentric mucosal rings-corrugated esophagus, crepe paper, pavement, long-section stricture, scars), histology (the number of eosinophil granulocytes of the esophageal tissue exceeds 15 eosinophil granulocyte/high-magnitude field of vision and biopsy samples from other parts of the digestive tract do not shows any significant difference), as well as allergic tests (high serum IgE level), pH monitoring (according to some studies, the presence of GERD may facilitate the formation of EoE), endoscopic ultrasound, manometric examinations and plain chest radiography with a water soluble contrast swallow [2, 4].
