A 10-year-old girl presented with a 4-month history of a large oropharyngeal mass and a left-side upper neck mass that remained stable in size since its discovery. The patient complained of dysphagia without significant weight loss but denied dyspnea, dysphonia, or otalgia. The patient was otherwise healthy, up-to-date on immunizations, and had no prior tobacco exposure.
On examination, a well-mucosalized, nonfluctuant, firm mass was palpable on the left side of the base of the tongue, causing leftward deviation of the tongue. There was also a palpable level II neck mass that was contiguous on bimanual palpation intraorally with no other cervical lymphadenopathy.
