Concurrent infection of pneumocystis pneumonia and pulmonary tuberculosis in an HIV-seronegative patient.

ABSTRACT

Co-infection with Pneumocystis jirovecii and Mycobacterium tuberculosis is rarely reported in patients without human immunodeficiency virus (HIV) infection. We describe the case of a 33-year-old HIV-negative female patient who was on long-term oral corticosteroids for rheumatoid arthritis and admitted with for respiratory distress and diffuse infiltrative pneumopathy in whom concurrent infection with Mycobacterium tuberculosis and Pneumocystis jiroveci was confirmed by bronchoalveolar lavage (BAL) fluid examination.
