A 68-year-old man was referred to the pulmonary clinic for evaluation of cough and a 5-cm right upper lobe mass. He was in his usual state of health until 1 year prior when he developed intermittent cough, wheezing, and sinus congestion. He denied any sputum production or hemoptysis. He also denied any fevers, chills, or weight loss. He had received various treatments within the prior 6 months, including short courses of oral prednisone, levofloxacin, and bronchodilators, without any relief of his symptoms.
