A case of lipoma of the deep lobe of the parotid gland.

Lipoma of the deep lobe of the parotid gland is extremely rare. A forty-two-year-old man presented with a painless, soft, and slow-growing mass in the left preauricular area. Ultrasonography and computed tomography findings were consistent with lipoma. The patient was treated with superficial parotidectomy and total excision of the mass with preservation of the facial nerve. Histologic findings confirmed the diagnosis. No recurrences were detected during 1.5 years in the postoperative period.
