BELTRAN M, Constanza; GARCIA M, Raimundo; ESPINO E, Alberto  y  SILVA A, Claudia. Eosinophilic Esophagitis: an emerging entity. Rev. Otorrinolaringol. Cir. Cabeza Cuello [online]. 2009, vol.69, n.3, pp.287-298. ISSN 0718-4816.  http://dx.doi.org/10.4067/S0718-48162009000300013.

Eosinophilic esophagitis (EE) is a primary disease of the esophagus, previously mistaken with gastroesophageal reflux disease (GERD). Its knowledge has developed over the last decade. EE is defined as the presence ofesophageal dysfunction symptoms (mostly dysphagia and food impaction) associated to at least 1 esophageal biopsy with 15 or more eosinophils in 1 high-power field and absence of GERD. Its prevalence is rising, affecting principally white boys and young males with previous history of atopy. EE would be caused by an allergic reaction to certain food and aeroallergens mediated by citoquines with genetic changes involved. Clinical presentation varies with age being dysphagia the most common symptom in all age goups. The diagnosis is clinical, endoscopic and histopathologic. It requires an endoscopy to evaluate mucosal findings and to take the biopsies. Treatment includes elimination diets and topical steroids. The purpose of this review is to analyze the current state of the definition, history, epidemiology, fisiopathology and the diagnosis of EE, with an emphasis on improving its suspicion index and initial management.

Palabras clave : Eosinophilic esophagitis; dysphagia; atopy.
