Squamous cell lung cancer presenting as a malar mass.

INTRODUCTION: Lung cancer metastasizing to the face has rarely been reported and is an even more unusual presentation. CASE: 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. DISCUSSION: 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.
