title: Upper aerodigestive tract cancer and the lung: a tale of two aspirations.
abstract: Patients with upper aerodigestive epithelial cancers frequently develop second primary cancers due to common risk factors or develop distant metastases depending on the locoregional status of the primary tumor. In most instances, the organ affected is the lung. Pulmonary spread usually occurs due to hematogenous or lymphatic dissemination. The following is a report of two patients with upper aerodigestive tract squamous cell carcinomas who developed lung metastases due to aspiration, a route not well documented in recent literature.
