A case of an 87-year-old female with pleomorphic adenoma of the tongue base is reported, with a review of the literature. The tumour had enlarged gradually over a period of three years, causing dysphagia and dysphasia. Computed tomography and magnetic resonance imaging showed that the tumour was exophytic and occupy the oropharynx with little extension into the muscle tissue. The tumour was resected by CO2 laser.
