== Clinical Summary ==

This 55-year-old white male had a long history of emphysema and a 60-70 pack-year smoking history. He was in his usual state of health until about one month before admission, at which time he developed increasing dyspnea on exertion. At the same time, his sputum increased from two tablespoons to half a cup of yellow blood-streaked sputum a day. Chest x-ray showed a right hilar mass. Sputum cytology revealed abnormal cells that were "positive for malignancy." He later developed pneumonia and fever. The patient expired soon thereafter.
