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.

Parotis bezinde onkositik lipoadenom: İnce iğne aspirasyon sitolojisi bulguları ile birlikte bir olgu sunumu

Öz

Tükürük bezinin onkositik lipoadenomu nadir görü- len bir tümördür. Elli altı yaşında erkek hasta sol parotis bezinde iki yıldır yavaş büyüyen kitle öykü- sü ile başvurdu. Kontrastlı bilgisayarlı tomografi incelemesinde sol süperfisyal ve alt derin lobda 7x6.5x6 cm boyutlarında solid iyi sınırlı parotis kitlesi saptandı. İnce iğne aspirasyon biyopsisinde görülen onkositik hücreler öncelikle Warthin tümörü veya onkositoma ön tanısını akla getirdi. Hastaya sol total parotidektomi uygulandı. Onkositik lipoa- denom tanısı konuldu. Altı aylık takipte yineleme izlenmedi. Parotisdeki onkositik proliferasyonların ve onkositik tümörlerin ayırıcı tanısında onkositik lipoadenom da düşünülmelidir
