The great majority of these arise from squamous cell carcinoma of the upper aerodigestive tract. A complete head and neck examination may reveal the cancer of origin, but examination under anesthesia with direct laryngoscopy, esophagoscopy, and bronchoscopy is usually required to fully evaluate the cancer and exclude second primaries.
