title: Metastatic pleomorphic adenoma.
abstract: We report a case of pleomorphic adenoma of the parotid with metastasis to the liver, following resection for local recurrence, which has only been described once before. The diagnosis was made by fine needle aspiration and the lesion was resected without complications. The patient is free of disease 4 years later. Histological features of malignancy were not present in any specimens from the original resection, the local recurrence and the metastatic lesion. It is difficult to say which patients with pleomorphic adenoma should be observed for the development of treatable metastases, but metastases have been reported to occur mainly after repeated resections for local recurrences.
