title: Metastases from the lung presenting as a parotid lump.
abstract: We report a case of a 59-year-old man who presented with a preauricular facial lump that was suspected to be a parotid malignancy based on fine needle aspiration. A chest radiograph and a computed tomogram showed a mass in the lungs and several metastases, and caused a diagnostic dilemma as to the origin of the parotid mass, which was later confirmed to be metastatic disease that had arisen from a carcinoma of unknown origin. Infraclavicular metastasis to the parotid is rare but should not be overlooked particularly in patients who present with coexisting conditions, or when cytological findings are atypical.
