Purpose of review: Lymphocytic esophagitis (LE) is an unusual esophageal condition defined by an increased number of lymphocytes in the esophageal epithelium. With few published studies of LE available, it is unclear whether LE is a truly distinct clinical entity or a histological manifestation of other known gastrointestinal disorders. This review summarizes recent studies of lymphocytic esophagitis.
Recent findings: Studies have suggested that LE may be related to eosinophilic esophagitis (EoE) or a manifestation of gastroesophageal reflux disease (GERD). There is an association between LE and Crohn's disease in children, but not in adults. Patients with LE frequently report symptoms of dysphagia and GERD. Treatment options for LE are limited and involve symptom management similar to treatment of EoE or GERD, including proton pump inhibitors (PPI), swallowed topical steroids, and endoscopic dilation. With no formal definition and a variety of clinical presentations and endoscopic findings, diagnosis and management of symptomatic LE patients is challenging for clinicians.
