[Clinical aspects and pathology of mycobacterial infections in AIDS. Pulmonary and extrapulmonary manifestations].

Infections with M. tuberculosis and other mycobacteria (atypical mycobacteria) are frequently found in patients with AIDS. They are almost always disseminated, and are associated with a spectrum of findings that is often unhelpful for the diagnosis. In the case of tuberculosis, typical granulomas are a major finding. The histological correlate of mycobacteriosis is histiocytosis; granulomas are rarely observed, and when they do present, are incompletely developed.
