Lymphocytic Esophagitis Presenting With Food Impaction.

Lymphocytic esophagitis (LyE) is a rare diagnosis made on esophageal biopsy whose pathogenesis is poorly understood. Since its appearance in the literature 15 years ago, it still remains an enigma due to its low prevalence. In this case report, a 71-year-old male presented with an episode of acute dysphagia due to food impaction. Urgent endoscopy was performed to fragment the food bolus. Repeat endoscopy showed a stricture, and lymphocytic esophagitis was found on esophageal biopsy. A proton pump inhibitor (PPI) was initiated with symptomatic improvement. With its increasing prevalence, lymphocytic esophagitis should be on the differential for causes of dysphagia.
