An Bras Dermatol. 2013 May-Jun;88(3):420-3. doi: 10.1590/abd1806-4841.20131812.

Abstract

Histoplasmosis is a systemic mycosis endemic in extensive areas of the Americas. The authors report on an urban adult male patient with uncommon oral-cutaneous lesions proven to be histoplasmosis. Additional investigation revealed unnoticed HIV infection with CD4+ cell count of 7/mm3. The treatment was performed with amphotericin B, a 2065 mg total dose followed by itraconazole 200mg/daily plus antiretroviral therapy with apparent cure. Histoplasmosis is an AIDS-defining opportunistic disease process; therefore, its clinical diagnosis must drive full laboratory investigation looking for unnoted HIV-infection.

Histoplasmose é infecção sistêmica endêmica em extensas áreas do continente Americano. Os autores relatam caso de paciente do sexo masculino, de zona urbana com lesões cutâneas e mucosas incomuns de histoplasmose. Investigação adicional posterior revelou infecção subjacente pelo HIV com contagem de células CD4 de 7/mm3. O tratamento foi realizado com anfotericina B, dose total de 2065 mg, seguido por itraconazol 200 mg/dia associado à terapêutica antirretroviral com cura aparente do quadro. Histoplasmose é enfermidade oportunística definidora da síndrome de imunodeficiência adquirida, portanto, diagnóstico clinico de histoplasmose implica em investigação laboratorial de infecção subjacente pelo HIV.
