Lymphoepithelial carcinoma of the submandibular gland is an extremely rare condition; therefore, no clear clinical features or established treatment is available for this. A 58-year-old Japanese man who came to our hospital with the complaint of swelling of the left submandibular region was diagnosed with stage IVa, T4aN2bM0 lymphoepithelial carcinoma of the submandibular gland. We also examined the relationship between the tumor and Epstein-Barr virus by Epstein-Barr virus encoded ribonucleoprotein in situ hybridization. The patient was treated by performing segmental mandibulectomy, neck dissection, mandibular reconstruction, and adjuvant chemoradiotherapy. After 2 years of treatment, good progress has been observed in the patient without any signs of recurrence. Here, we have reported the treatment of a patient with lymphoepithelial carcinoma of the submandibular gland using literature review.
