Abstract:
A case of malignant oncocytoma of the parotid gland in a 32-year-old male is presented. Ten months after parotidectomy an undifferentiated carcinoma, in which oncocytes still could be recognized, developed in the operated area. According to the literature available to us, this is the second reported case in which malignant transformation in a benign oncocytoma of the salivary gland has been observed.
