Özet
Oncocytic carcinomas are uncommon; they represent 11% of all oncocytic salivary gland neoplasms, 0.5% of all epithelial salivary gland malignancies and 0.18% of all epithelial salivary gland tumors. A 65-year-old woman was admitted to our ENT clinic with a history of a painless left preauricular mass. No lymph node was palpable on either side of her neck. Computed tomography demonstrated a 3x3-cm solid lesion in the left parotid gland. As oncocytes and atypical cells were seen at the cytologic examination of a fine-needle aspiration biopsy, this finding suggested a malignant epithelial tumor. Total parotidectomy by preserving the facial nerve was performed. The result of the pathologic examination was oncocytic carcinoma regarding histopathologic and immunohistochemical findings and especially the invasive growth pattern. We preferred a close follow-up to an elective neck dissection, and reserved the neck dissection for a recurrence. The prognosis of oncocytic carcinomas is not well known because of their low incidence. Further investigation of the prognosis of patients with oncocytic carcinoma of the parotid gland is warranted as more cases are reported.
