The Case of the Late Head and Neck Lymphedema

Samuel, a 55-year-old patient with a history of T3N1M0 oropharyngeal HPV+ cancer on the base of his tongue, underwent surgery followed by 70 Gy of intensity-modulated radiation over seven weeks with concurrent weekly cisplatin. He responded well and had a positron emission tomography (PET) scan three months post-treatment that showed no cancer. Two months later, Samuel calls the triage line to report swelling on the left side of his neck, the same area where he first noticed a lymph node that led to his initial diagnosis.
