We report the case of 57-year-old man with metastasis of squamous cell carcinoma to the right subdigastric lymph nodes from an unknown primary site.
Although the first smear test of sputum was classified as V, the primary site could not be identified on further examination. Total neck dissection on the right side was performed after 2 courses of chemotherapy. Two more courses of chemotherapy were given after the operation, but radiotherapy was not performed.
The patient is free of recurrence and metastasis about 2 and a half years after treatment.
