Eosinophilic esophagitis (EE) is an increasingly common subset of eosinophilic childhood disorders, although adults may also be affected. During the last decade, the frequency of EE diagnosis has increased substantially, but its recognition by pathologists and clinicians is still unclear. Many patients have a history of allergic rhinitis, asthma, or food allergies.. The literature substantiates that food allergies can cause EE in children in more than 90% of cases, and detailed retrospective and prospective studies have determined that the elimination of certain dietary elements leads to the alleviation of symptoms. This finding differs from that of adults with EE, who are mainly sensitized to aeroallergens; for these patients, the impact of eliminating cross-reacting plant-derived food allergens does not appear to be an efficient therapeutic measure.
