Dysphagia with a normal endoscopy presents a challenge in diagnosis. While encountering such cases, the clinicians should remember the following points:
Dysphagia with a normal endoscopy should prompt consideration of eosinophilic esophagitis (EOE) as a potential differential diagnosis.
Conduct esophageal biopsies for all patients presenting with dysphagia, especially when the endoscopy appears normal.
EOE has the potential to mimic motility disorders during high-resolution manometry testing. ï‚© Skin lesions are an important clue in the diagnosis.
