Case PresentationA 70-year-old man was referred for evaluation of recurrent respiratory infections requiring antibiotics and chronic cough over 3 years. Two months prior to presentation, he started to develop blood-tinged sputum but not frank hemoptysis. He otherwise denied any fever, chills, night sweats, or weight loss. He had dyspnea during the respiratory infections but not otherwise. His medical history was significant for chronic rhinitis without sinusitis and a low serum IgM level. He was a never smoker and a farmer but otherwise had no significant or specific exposures or travel history. His family history was significant for alpha-1 antitrypsin deficiency in his mother.Published by Elsevier Inc.
