Co-infection of disseminated histoplasmosis and tuberculosis in an AIDS patient.

Histoplasmosis is a fungal disease caused by the dimorphic fungus , recognized as an AIDS-defining illness since the Center for Disease Control's revision criteria in 1985. This infection is reported to be present in 5-20% of AIDS patients, and in 95% of the cases it is manifested in its disseminated form. Serum antibodies and/or antigen research can make diagnosis, but the demonstration of the agent by culture or histopathological examination remains the gold standard methods.
