title: Mixed pulmonary infection in an immunocompromised patient: a rare case report.
abstract: Patients who are immunocompromised are predisposed to a variety of common and uncommon pulmonary infections. We report a case of mixed pulmonary infection by drug resistant tuberculosis with a nocardiosis in a 49-year-old man who was a known case of chronic obstructive pulmonary disease, on prolonged corticosteroid use with diabetes mellitus. Chronic use of corticosteroids is a predisposing factor for opportunistic infections, such as nocardiosis or tuberculosis. Since such a mixed infection is rare, maybe a combined approach to therapy early in the course of disease would be effective in such cases.
