title: Oncocytic lipoadenoma of the parotid gland: a case report with fine needle aspiration cytology findings.
abstract: Oncocytic lipoadenoma of the salivary gland is a rarely encountered tumor. A 56-year-old man presented with a two-year history of a slow-growing mass of the left parotid gland. Computed tomography scan with contrast showed a 7x6.5x6 cm well-circumscribed solid parotid mass of the left superficial and deep lobe. Fine-needle aspiration yielded oncocytic cells exclusively, suggesting Warthin tumor or an oncocytoma. Left total parotidectomy was performed. A diagnosis of oncocytic lipoadenoma was made. At six-month follow-up no evidence of recurrence has been noted. Oncocytic lipoadenoma should be considered in the differential diagnosis of oncocytic proliferations and oncocytic tumors in the parotid gland.
