A 48-year-old man presented with a 6-month history of progressive swelling over the left lateral pharyngeal wall. He complained of mild dysphagia during swallowing but was otherwise in good health. His medical and family histories were unremarkable. Physical examination revealed a medial bulge in the left lateral pharyngeal wall, with smooth overlying mucosa. It extended from the nasopharynx to the oropharynx and displaced the left tonsil medially. Examination of the head and neck and the rest of the oral cavity showed no other abnormalities, and no neurologic deficits were noted.
