A 33-Year-Old Man With Acute Hemoptysis.

A 33-year-old man with a medical history of childhood exercise-induced asthma presented to the ED with 2 days of hemoptysis. He described the hemoptysis as bright red blood with clots, approximately 100 cm in total. He denied prior hemoptysis, pulmonary infections, or exposure to TB. Years ago he had an episode of gross hematuria, but a urologic workup was unrevealing.
