[Subacute diseminated histoplasmosis in HIV patients].

Histoplasmosis is a cosmopolitan mycosis caused by Histoplasma capsulatum. It is endemic of Río de la Plata's riverbed and in immunocompromised patients may be deadly. We present two patients with Human Immunodeficiency Virus diagnosed with subacute disseminated histoplasmosis, which is a marker of Acquired Human Immunodeficiency Syndrome. This situation increases the morbimortality, thus forcing clinicians to diagnose and treat rapidly in order to avoid fatal outcomes.
