[Clinical Picture] Large parapharyngeal mass: a challenging differential diagnosis

A 35-year-old male patient presented at the Otolaryngology Department of the Policlinico Umberto I, Sapienza University of Rome (Rome, Italy) in February, 2017 with a 14-month history of breathing difficulties and dysphagia. Endoscopic examination showed a bulking in the right parapharyngeal space, extending into the oropharynx, dislocating the pharyngeal wall and causing a noticeable obstruction of respiratory tract; no externally visible cervical mass was present. Laboratory investigations and radiography of the chest were normal.
