Cutaneous histoplasmosis in patients with acquired immunodeficiency syndrome.

Since 1987, the US Centers for Disease Control and Prevention has considered disseminated histoplasmosis an acquired immunodeficiency syndrome (AIDS)-defining illness. Cutaneous manifestations of disseminated disease are diverse and often present as a nondescript rash with systemic complaints. Diagnosis is best established by histopathologic examination with appropriate stains for fungal organisms. Skin lesions often resolve within weeks of initiating treatment. We detail a case of cutaneous histoplasmosis and review its epidemiology, common presentations, diagnosis, and treatment options.
