A very unusual cause of persistent cough diagnosed by bronchoscopy

摘要

A 68-year-old nonsmoking male presented in 2007 with a history of hiatal hernia, long-standing bronchial asthma requiring high-dose oral corticosteroids on a chronic basis, and visceral leishmaniasis (VL) with shock secondary to acute adrenal gland insufficiency. He reported worsening dyspnea and a persistent cough for several months. The patient showed good treatment compliance and an adequate control of factors that could favor the persistence of the asthma symptoms (such as hiatal hernia).
