title: Squamous cell lung cancer presenting as a malar mass.
abstract: BACKGROUND
  Lung cancer metastasizing to the face has rarely been reported and is an even more unusual presentation.
  
  
  METHODS
  This is the case of a 49-year-old man diagnosed with squamous cell carcinoma of the face, scheduled for resection. Preoperative radiographs revealed a left upper lobe mass, found to be squamous cell carcinoma. Diagnosis was changed to Stage IV primary lung cancer. The patient did not undergo resection.
  
  
  CONCLUSIONS
  No previous cases of primary lung cancer presenting as a malar mass have been reported. Facial lesions can be the presenting feature of primary lung cancer. Discovery of the true primary lesion can alter therapy and prognosis.
