Circumferential squamocellular papilloma of the cervical esophagus, a rare cause of dysphagia. A case report.

A case report of a patient with circumferential benign squamous cell papilloma of the cervical esophagus is presented. The location, appearance and symptoms of the lesion are unusual, and the etiology and treatment are discussed. The case is important for otorhinolaryngologists, because the widely used method to examine the upper gastrointestinal tract, fiberesophagogastroscopy, does not offer optimum conditions to investigate the proximal esophagus. The rigid hypopharyngoesophagoscopy under general anesthesia is the method of choice for this region, a method familiar to otorhinolaryngologists.
