A 37-Year-Old Man With Nonresolving Pneumonia and Endobronchial Lesion

A previously healthy, immunocompetent 37-year-old man was hospitalized with a 3-month history of intermittent fevers and cough with mucopurulent sputum preceded by flu-like symptoms. Five episodes of similar symptoms had prompted two hospitalizations and three courses of outpatient antibiotics. The fever would subside with treatment but intermittent dry cough persisted. There was no history of weight loss, night sweats, wheezing, arthralgia, skin rash, hemoptysis, recent travel, sick contacts, or high-risk sexual behavior. He was a nonsmoker with no alcohol or recreational drug use. He was an accountant in the military with no history of significant organic or inorganic dust exposures.
