Abstract
An 80-year-old man presented with a 5-day history of hemoptysis, mild shortness of breath on exertion, fatigue, and malaise. He denied chest pain or fever. He had a history of hypertension, congestive heart failure, and left nephrectomy for renal cancer 10 years earlier; he was a former cigarette smoker with a 50 pack-year history, having quit 5 years prior to presentation. The patient did not report any recent travel history or occupational or animal exposures, and he did not have gastroesophageal reflux. Medications included diltiazem hydrochloride, irbesartan, hydrochlorothiazide, and ranitidine.
