Since 1999 we have observed three cases of imported histoplasmosis in our hospital. One was an immunocompetent individual and two further patients were immunosuppressed (renal transplantation and HIV infection C3). Two patients were born in endemic areas (Equatorial Guinea and Ecuador) and a third patient had a history of previous travel to the Peruvian Amazonia. The different clinical presentations and diagnostic tools of histoplasmosis are discussed.
