Lymphocytic esophagitis - A little-known cause of dysphagia.

Abstract

Lymphocytic esophagitis is a little-known entity whose cause is not fully established, and which basically presents with dysphagia. It is characterized by the presence of an infiltrate mainly formed by lymphocytes and other signs of epithelial damage in the absence of other granulocytes. The lack of knowledge about this pathology as well as standardized diagnostic criteria complicates its diagnosis. We present the case of an 84-year-old male with dysphagia and pathological findings compatible with lymphocytic esophagitis, requiring several lines of treatment and even endoscopic dilation with subsequent clinical improvement.
