[Disseminated aspergillosis in acute leukemia probably chemically-induced]

One case of invasive aspergillosis in patient with myeloblastic leukemia probably induced by chimiotherapy is reported. Aspergillosis is a severe infection in immunodepressed host with 70 to 80% of mortality. Early diagnosis can be often carried by broncho-alveolar lavage, route of entry is always pulmonary one. Rapidly established antimycotic treatment can avoid death. Laminar air flow rooms and air spores numeration allow prevention of this infection in the immunodepressed host.
