Abstract:
A 29-year-old man with a history of oculocutaneous albinism presented to the ED complaining of progressive dyspnea on exertion. One month prior to admission, the patient had begun to experience worsening dyspnea provoked by routine household activities. Additionally, he had developed a nonproductive cough, exacerbated by cold weather. He denied associated chest pain, hemoptysis, fever, chills, or night sweats. He denied any new exposures or sick contacts in the recent past. A review of systems was significant for a history of epistaxis and frequent bruising. Born in Honduras, he had immigrated to the United States approximately 10 years prior to his presentation to our facility. Furthermore, there was no family history of albinism, bleeding disorders, or pulmonary disease.
