Oncocytic tumors of salivary glands are rare. Diffuse oncocytosis is the rarest lesion among 3 principal groups of oncocytic lesions as classified by WHO. Only seven cases have been previously reported in the literature. We report a case of diffuse hyperplastic oncocytosis of the parotid gland in a 63-year-old male with a brief review of literature. To the best of our knowledge this is the first case from Indian subcontinent.
