Lymphocytic esophagitis is a new and rare entity, first described in 2006. Histologically, the esophageal mucosa is characterized by a dense peripapillary lymphocytic infiltrate and an intercellular edema without granulocytosis. To this day, it is not yet considered as a disease. Its etiology and clinical significance are still unclear. The predominant symptom is dysphagia and the main endoscopic feature is a normal esophagus. The absence of relationship between lymphocytic esophagitis and specific clinical conditions justifies further studies. Currently, it remains a histologic entity.
