Eosinophilic esophagitis: Current status = Esofagitis eosinofílica: estado actual

Eosinophilic esophagitis is an infiltration of the esophagus by eosinophils, presumably of allergic origin; it may affect both children and adults. In the latter, it is more common in middle-aged men and its main clinical feature in this population is the presence of dysphagia. Knowledge on this disease has had great development in the last 10 years with better understanding of its pathophysiology, and many studies are being done to evaluate different therapeutic alternatives. We present a review of the literature on eosinophilic esophagitis describing the epidemiology, clinical manifestations, pathophysiology, differential diagnosis and therapeutic options.
