A 77-year-old man was referred for evaluation of a left chest mass found on a routine radiograph during hospitalization for a myocardial infraction. The patient underwent successful coronary stenting for occluded right coronary and left circumflex coronary vessels and remained asymptomatic.
His medical history was significant for hypertension, hyperlipidemia, benign prostatic hypertrophy, and peripheral vascular disease. He had undergone a carotid endarterectomy 2 years prior to this hospital admission. His medications included atenolol, aspirin, clopidogrel, pantoprazole, simvastatin, tamsulosin, and amlodipine. His social history was remarkable for cigarette smoking (1 pack a day for > 50 years) until he quit 4 years ago. He was retired from the merchant marine, and his work involved ship repair for several weeks at a time. No clear asbestos exposure could be established. His purified protein derivative status was negative. His vital signs, the findings of physical and cardiopulmonary examinations, and results of basic laboratory investigations were unremarkable on presentation.
