title: Oxyphilic granular cell adenoma (oncocytoma) of the esophagus.
abstract: An oncocytoma of the esophagus is presented. The patient's chief complaint was dysphagia, and barium swallow suggested cricopharyngeus muscle hypertrophy. Exploration revealed an intramural mass in the cervical esophagus. Enucleation resulted in relief of symptoms. Pathological and immunohistochemical analysis demonstrated an oncocytoma of thyroid origin.
