AbstractA 65-year-old man experienced a cough and mild hemoptysis suddenly one morning. He was prescribed tranexamic acid and carbazochrome salicylate by the local clinic at the first visit, and his hemoptysis stopped. However, 2 days later, he experienced recurrent hemoptysis that was prolonged intermittently. He had slight dyspnea and chest discomfort, but no other symptoms, such as sputum, fever, or chest pain. He was referred to our hospital for further assessment of hemoptysis. He had experienced mild hemoptysis of unknown causes 8 years earlier without recurrence until this episode. He had bronchial asthma that was treated with an inhaled corticosteroid and hypertension and hyperuricemia that were untreated with medication. He had no known allergies or family history of lung disease. He did not smoke. The patient denied alcohol consumption, any recent travel, or exposure to TB.Copyright © 2023 American College of Chest Physicians. Published by Elsevier Inc. All rights reserved.
