Abstract
Histoplasmosis is a systemic mycosis caused by the dimorphic fungus Histoplasma capsulatum, a facultative intracellular parasite of the system. It is predominantly found in North America, primarily Midwestern and Southeastern United States. Transmitted by inhalation of airborne fungal conidia, H. capsulatum can cause mild to severe respiratory illness. Dissemination of histoplasmosis occurs in immunocompromised patients following initial infection, reinfection, or reactivation of the latent foci. Histoplasma initially disseminates to organs rich in reticuloendothelial cells, but it can infect any organ/organ system, including central nervous system (CNS), gastrointestinal tract (GIT), skin, and adrenal glands, etc. Disseminated histoplasmosis is considered one of the acquired immunodeficiency syndrome (AIDS)-defining infections, and it usually occurs in HIV-infected individuals with a CD4 count<200/mm3.
