Oncocytoma is a rare benign tumor of the salivary glands. It Comprises 0.1% to 1% of the parotid tumors. Characteristically, the oncocytoma occurs in women in the sixth to seventh decades, almost arises in the parotid gland. A 51-year-old female patient visited our hospital with the chief problem of left infra-auricular painless mass for two years without facial palsy or lymph node swelling. Under the impression of benign parotid tumor, she received superficial parotidectomy. The frozen section and pathology revealed oncocytoma. She stood the operation well without any sequela except temporary facial palsy and Frey’s syndrome on the left side. She was regularly followed up for one year without recurrence.
