Dysphagia and rings in the esophagus can occur from any inflammatory condition. Even eosinophils may be present in GERD alone. EOE typically requires a confirmatory biopsy from the upper and lower esophagus showing eosinophilic infiltrates. Desquamative conditions that should be excluded include bullous pemphigoid and lichen planus. These typically require deep biopsies and special immunofluorescence staining; thus, communication between endoscopist and pathologist is critical.
