Eosinophilic esophagitis (EoE) is one of the most common causes of reflux-like symptoms and feeding problems in children and food impaction and dysphagia in adults with a prevalence of 1:2500. Therapeutic options include diet, use of swallowed corticosteroids, or dilation. In the last several years, recent clinical and translational researches have identified some common and distinctive features, for example, the varying response to diet and medications. As EoE shares some characteristics with both asthma and inflammatory bowel disease, the advances in these fields suggest that various phenotypes may also exist in patients with EoE. Here, we provide a rationale for EoE phenotypes and provide some suggestions for potential phenotypes based on histology, molecular signature, response to therapy or dietary therapy.
