Lymphocytic Esophagitis Mimicking Allergic Esophagitis: A Case Report.

Lymphocytic esophagitis (LE) is a rare inflammatory condition of the esophagus, characterized by intraepithelial lymphocytic infiltration of the esophageal mucosa. Despite its increasing recognition recently, standardized guidelines for diagnosis and management are still lacking. LE is frequently associated with conditions that alter esophageal pH, including gastroesophageal reflux disease (GERD), Crohn's disease, and diabetes mellitus. This report describes a 55-year-old male who presented with dysphagia and intermittent heartburn. Esophagogastroduodenoscopy (EGD) revealed LE along with incidental Helicobacter pylori gastritis. Management typically focuses on addressing underlying conditions, with proton pump inhibitors (PPIs) and topical steroids being the most common therapeutic approaches. The discussion highlights the prevalence, diagnostic challenges, and treatment strategies for LE.
