A 34-year-old man presented with carcinoma of the glottis, stage T4N1M0, and underwent a total laryngectomy with bilateral selective neck dissection. His postoperative recovery was uneventful, and he had resumed full oral intake by postoperative day 8. Six weeks after surgery, a painless swelling developed in the right submandibular region. Physical examination revealed a firm, nonpulsatile 3×2-cm mass with restricted mobility. The scar had healed well and the tracheal stoma site was healthy. The findings of the rest of the physical examination were normal.
