title: A case of eosinophilic esophagitis with atypical clinical course.
abstract: Eosinophilic esophagitis is a rare chronic disease that mainly occurs in middle-aged males. Treatment with a glucocorticoid and/or proton pump inhibitor is usually necessary to relieve unpleasant symptoms. An 83-year-old female patient with dysphagia and heartburn was diagnosed with eosinophilic esophagitis based on endoscopic findings, while histological examination identified dense infiltration of intraepithelial eosinophils. The symptoms and eosinophil infiltration spontaneously disappeared without any treatment approximately 2 months later. No obvious lifestyle or dietary changes to explain elimination of possible antigens were identified in this case. We report an atypical case of eosinophilic esophagitis with spontaneous regression.
