[Disseminated histoplasmosis in patients with AIDS. 2 case reports]

Histoplasmosis is endemic in some areas of United States and in South America, and generally causes an acute self-limiting respiratory infection. In elderly and immunosuppressed patients the infection can spread through the blood, causing a severe systemic illness. Here we describe two cases of disseminated histoplasmosis in AIDS patients. The first was observed in an Italian woman who had never visited endemic countries, and was recognized only at autopsy; the second was observed in a trans-sexual patient, arrived in Italy from Brazil. Clinical suspicion of histoplasmosis is important in immunocompromised patients of non-endemic areas as symptoms are often aspecific and misdiagnosis is frequent.
