Idiopathic eosinophilic esophagitis is a part of disorders that comprise eosinophilic gastroenteritis, a condition characterized by eosinophilic infiltration of the gastrointestinal tract. Its clinical feature depends on the type of layer and location involved. A 56-year-old man presented with dysphagia and abdominal pain. Endoscopic ultrsonography and esophageal manometry showed definite smooth muscle hypertrophy of the esophagus and vigorous achalasia like motility disturbance. We report a case of eosinophilic eosphagitis that resolved by steroid treatment, with a review of relevant literatures.
