Eosinophilic esophagitis as a cause of dysphagia of 10 years of evolution

: A new case of eosinophilic esophagitis is reported in a young male with a 10-year history of dysphagia who did not present manifestations of allergy, reflux or other involvement of the digestive tract by eosinophilic infiltration. A review of the literature up to the present is provided with emphasis on the fact that this is an entity to take into account in the differential diagnosis of dysphagia, especially in young people and that this disease is probably underdiagnosed.
