The patient is a 37-year-old hospital employee and current smoker with a 10 pack-year smoking history, who presented with dyspnea, chest pain, and weight loss. She was in her usual state of health until 4 months prior to admission when she developed intermittent left-sided chest pain, cough productive of scant yellow sputum, fevers, and anorexia. Initial chest radiograph was normal and her outpatient physician prescribed azithromycin, which she took without improvement. ⋯ Her most recent travel was to the Midwestern United States, without significant outdoors exposure. Review of systems was positive for wheezing, anorexia, and arthralgias of both knees and the left ankle and wrist. There was no hemoptysis, leg swelling, visual changes, palpitations, or muscle weakness.

A 64-year-old man presented for consideration for lung transplant. He had a history of previous tobacco use, OSA on CPAP therapy, and gastroesophageal reflux disease. He worked as a design engineer. ⋯ Pulmonary function tests (PFTs) were consistent with a restrictive pattern, decreased diffusing capacity (Dlco), and a preserved residual volume over total lung capacity ratio. The patient was prescribed systemic corticosteroids with no improvement of his symptoms. Repeat PFTs showed further decline of Dlco, and he was referred for lung transplant evaluation.
