A 75-Year-Old Man With Irregular Solid Components Within an Emphysematous Bulla.

A 75-year-old man presented to our hospital with cough and sputum for more than a year. Eight months previously, the patient was admitted to a local hospital, and his symptoms were relieved after symptomatic treatment (expectorants and antitussives). Three months ago, he was admitted to our hospital, and his symptoms improved with antiinflammatory therapy. He had a 30-pack-years history of smoking (20 cigarettes/day) and a history of drinking (200 g liquor per day). The patient had no history of genetic disorders or cancer. He did not present with fever, dyspnea, hemoptysis or chest distress, and there was no history of weight loss since onset. [ABSTRACT FROM AUTHOR]
