Discrete cutaneous lesions in a critically ill patient treated only for AIDS and miliary tuberculosis: a case report of disseminated histoplasmosis


Histoplasmosis is a systemic mycosis caused by the dimorphic fungus Histoplasma capsulatum, with disseminated histoplasmosis (HD) being one of its clinical forms. As a consequence of the HIV-AIDS pandemic, HD has become prevalent not only in regions that are recognized as endemic but also in areas not considered endemic, such as Europe and Asia. Its clinical manifestations are varied and mimic several infectious diseases, mainly tuberculosis. In endemic areas, it is the first manifestation of AIDS in 50 to 70% of patients. The diagnosis of histoplasmosis is difficult and HD can lead to death if not diagnosed early and if proper treatment is not instituted. The present report presents a patient with a recent diagnosis of HIV-AIDS, in treatment for miliary tuberculosis, who was diagnosed with disseminated histoplasmosis because of his dermatological manifestations.
