Eosinophilic Esophagitis.

Eosinophilic esophagitis (EoE) is a chronic allergic inflammatory disease of the esophagus that effects children and adults. Typical symptoms of EoE typically involve failure to thrive and vomiting in small children, and dysphagia and food impaction in adolescents and adults. However, throat clearing, choking, gagging, and hoarseness have also been observed and these issues often bring patients to first seek otolaryngology and pulmonary evaluation. Diagnosis is only made by esophogastroduodenoscopy with biopsy, so clinicians must have a low threshold for considering eosinophilic esophagitis even in the absence of frank gastrointestinal symptoms.
