Eosinophilic esophagitis is a form of esophagitis characterized by an abundance of intraepithelial eosinophils. It affects both children and adults and is believed to be an allergic disorder. Clinically, the predominant symptom is dysphagia and there is an association with atopy, asthma, allergic rhinitis, and peripheral blood eosinophilia. On endoscopy, patients with eosinophilic esophagitis demonstrate characteristic esophageal rings referred to as "trachealization" of the esophagus.
The microscopic findings may overlap with Gastroesophageal Reflux Disease (GERD), however eosinophilic esophagitis characteristically demonstrates a greater degree of intraepithelial eosinophils (typically >15/HPF) and greater severity within the proximal esophagus. The eosinophils are typically found within the superficial portions of the squamous mucosa and may aggregate to form eosinophilic microabscesses.
Alterations to diet and corticosteroids, either topical or systemic, may be required to treat eosinophilic esophagitis.
