Invasive pulmonary aspergillosis complicating chronic obstructive pulmonary disease in an immunocompetent patient.

Immunocompromised individuals are susceptible to pulmonary aspergillus infection, but invasive aspergillus infection is extremely rare in the presence of normal immunity. We report a case of invasive aspergillosis in an immunocompetent 63-year-old male with chronic obstructive pulmonary disease (COPD). Patients with COPD may be at risk for developing pulmonary aspergillus infection, which should be considered as a diagnostic possibility in patients with unresolving pulmonary infection.
