Parotid pleomorphic adenoma with solitary renal metastasis.
Bhutta MF., Dunk L., Molyneux AJ., Tewary A.
We present a rare case of renal metastasis of a recurrent pleomorphic adenoma of the parotid gland in an elderly woman. Metastasising pleomorphic adenoma shows malignant clinical behaviour, and although it appears histologically benign, there may be unknown molecular features that determine its unusual ability to spread.
