A true malignant mixed tumor (biphasic malignancy) is an extremely rare tumor in the minor salivary glands. A 58-year-old female was referred to us with a mass of the buccal mucosa. Examination revealed a left bilobular buccal mass with submandibular lymphoadenopathy. The mass was removed and a left modified neck dissection done. Pathological examination subsequently confirmed a diagnosis of true malignant mixed tumor, the first documented case of such tumor in the buccal mucosa.
