Lymphocytic esophagitis and ringed esophagus

Lymphocytic esophagitis is an uncommon condition characterized by the presence of intraepithelial lymphocytosis and lack of eosinophils in the esophageal biopsy samples. The main clinical manifestations include dysphagia, heartburn, and vomiting; endoscopic changes are absent in up to 30% of cases, and may mimic the common gross aspects of an eosinophilic esophagitis as rings, longitudinal furrows, and stenosis. The authors emphasize the role of this diagnosis confirmation as early as possible, with prompt and adequate management aiming to avoid eventual unfavorable outcomes. The objective of this manuscript is to emphasize the case study of an infrequent entity.
