'Non-resolving' pneumonia.

A 47-year-old man presented with symptoms of fever and productive cough secondary to a left upper lobe pneumonia. He had received more than three courses of antibiotics over a 2-year period. Review of serial radiographic exams including chest x-ray and CT scans revealed consolidation of the left upper lobe. Lack of response to antibiotics prompted invasive testing with bronchoscopy which revealed a growth in the left main bronchus. Histopathology revealed squamous cell carcinoma.
