Dyspnea in a 30-Year-Old Hispanic Man With Albinism

A 30-year-old albino Hispanic man, born in Puerto Rico, presented with a 1-month history of dyspnea, initially occurring on exertion, and gradually progressing to occur at rest. Medical history included a platelet disorder associated with easy bleeding diagnosed about 15 years earlier; this condition had not required treatment. He was not taking medications and had no surgical procedures. He had been advised to avoid aspirin because of his platelet abnormality. He had quit smoking 13 years previously and had no history of intravenous drug abuse or homosexual activity. There was no family history of lung disease.
