PY - 2020 T2 - Current Medical Diagnosis and Treatment 2020 AB - In older adults, 80% of firm, persistent, and enlarging neck masses are metastatic in origin. The great majority of these arise from squamous cell carcinoma of the upper aerodigestive tract. A complete head and neck examination may reveal the tumor of origin, but examination under anesthesia with direct laryngoscopy, esophagoscopy, and bronchoscopy is usually required to fully evaluate the tumor and exclude second primaries.
