Metastasis of oral cancer to the facial lymph nodes, especially to the mandibular lymph nodes is rare. We report a case of buccal mucosal carcinoma with mandibular lymph node metastasis. A 70 year-old-man with right buccal squamous cell carcinoma （T1M0N0） underwent surgical excision. Three months after the surgery, metastasis to the submandibular node was detected. The patient underwent supra-omohyoid neck dissection. But a further 2 months later, another 20 × 20 mm sized mass was observed superficially to the horizontal ramus of the mandible. The mass lesion was diagnosed with metastatic mandibular lymph node by CT and MRI. The lymph node was resected and postoperative irradiation was added. The patient died of the mandibular node recurrence 7 months after operation.
