[Oncocytic carcinoma of the parotid gland: a case report]

Abstract

Approximately 3% of all head and neck neoplasms originate in the parotid gland and less than 1% are oncocytic. We present the rare case of a 63-year-old woman with oncocytic carcinoma of the parotid gland with facial nerve invasion and discuss the characteristics of this rare entity. Based on the results of medical history, physical examination, computed tomography and postoperative histopathological diagnosis, oncocytic carcinoma of the parotid gland was diagnosed. Treatment involved complete parotid gland removal and right neck dissection. Adjuvant radiotherapy and chemotherapy were followed by operation. As of 9 months following surgery, no recurrence has been identified, but long-term results are undefined.
