A 47-year-old woman presented with a 2-month history of a left infra-auricular mass with mild tenderness. She was otherwise healthy and had no family history of cancer. Physical examination demonstrated a 2.0 × 2.0-cm, firm, fixed mass over the left parotid region, an intact oral mucosa, and no palpable lymphadenopathy. Fiberoptic laryngoscopy revealed no visible tumor in the larynx or the pharynx. Computed tomography of the patient's face revealed at least 4 enhanced nodular lesions in the superficial and deep lobes of the left parotid gland, with the largest one measuring 2.3 cm in greatest dimension (Figure 1). The results of laboratory investigations were normal.
