Pleomorphic adenoma is the most common benign tumor arising in major salivary glands and is rare in minor salivary glands. The most common site is the palate, and only 9 have been recorded occurring at the base of the tongue.
A 85-years-old woman seen for month-long dysphagia was found in Magnetic resonance imaging (MRI) to have a large round mass on the left side of the oropharinx, the lesion showed high intensity in T2 weighted imaging. The tumor and, adjacent muscle tissues 5 mm wide were transorally resected by harmonic scalpel. Histological examination showed a benign pleomorphic adenoma originating in the minor salivary gland at the tongue base.
