Lymphoepithelial carcinoma of the salivary gland is rare and manifests ethnic and geographic preferences. We report one such case in the parotid gland of a 55-year-old man with a painless mass in the left parotid region without facial nerve paralysis. The pathological lymph-node diagnosis of lymphoepithelial carcinoma necessitated total parotidectomy, left neck dissection, and facial nerve grafting followed by postoperative radiotherapy. In situ hybridization showed negative EBER, but serological results showed high VCA-IgA and anti-EBNA titers. The man remains free of locoregional recurrence and distant metastasis in the 3 years since surgery.
