In a literature review we found 22 published cases of disseminated histoplasmosis in patients with AIDS in Spain since All but two were men under 50 years old. Nineteen had been born or had lived in endemic areas. The uistoplasmosis of histoplasmosis was established by culture of bone marrow biopsy in 10 cases.

This data shows the importance of starting therapy with amphotericin B as soon as possible and then continuing with itraconazole, since all the patients who did not receive any antifungal therapy, or were treated with amphotericin B alone, died.
