[Oncocytoma of the parotid gland: a case report].

Oncocytoma is a rare benign salivary gland tumour with an incidence rate about 1-2%. It is located in the parotid gland in 82% of cases. The aging mitochondrial hypothesis could explain the predilection between 70 and 90 years. Clinical and radiological features of the parotid oncocytoma are not different from those of the others parotid benign tumors. We report a case of oncocytoma of the left parotid gland in a 69 years woman in whom fine needle aspiration cytology (FNAC) was for a pleomorphic adenoma. Through this case we highlight the importance of histopathology in the positive diagnosis of parotid oncocytoma as well as in it's differential diagnosis and also the place of FNAC.
