Synchronous parotid myoepithelioma and Warthin's tumor.

We present a case of an 84 yr old man who underwent resection of a slowly enlarging parotid mass. Macroscopic examination of the lesion revealed 2 distinct tumor foci which were shown histologically to be a typical Warthin's tumor with a separate tumor composed entirely of clear cells. Immunohistochemical studies of the clear cell tumor confirmed its myoepithelial nature. This is the first documented case of a coexistent Warthin's tumor and a myoepithelioma.
