Not your typical chronic obstructive pulmonary disease exacerbation: Aspergillus tracheobronchitis in a nonclassical immunocompromised host.

The present study reports on a 72-year-old female initially treated as a presumed chronic obstructive pulmonary disease (COPD) exacerbation, but she was ultimately discovered to have Aspergillus tracheobronchitis. Bronchoscopic findings were characteristic, revealing diffuse plaque-like inflammatory lesions extending from midtrachea into the mainstem bronchi. Evidence suggests that the rise in cases is attributable to the growing number of individuals who are immunocompromised secondary to underlying disease, combined with the expanding number of patients receiving glucocorticoids and immunomodulating medications to treat chronic, nonmalignant disorders. The present observations emphasize the importance of including Aspergillus tracheobronchitis in the differential diagnosis for patients receiving medications with immunosuppressive potential that present with dyspnea, cough, or fever and who fail to improve with empiric antimicrobial therapy.
