Scedosporium prolificans fungaemia in a patient with acute lymphoblastic leukaemia

Aggressive chemotherapy and immunosuppressive treatment may prolong patients' life, but influence the risk of severe, life-threatening infections. Here, we report the case of a 21-year-old caucasian female who developed a disseminated infection of Scedosporium prolificans after allogenic stem cell transplantation performed for treatment of relapsed acute lymphoblastic leukaemia. The pathogen was isolated from the blood and identified on the basis of its macroscopic and microscopic morphological features. The empirical treatment with amphotericin B provided no improvement. However, introduction of intravenous voriconazole resulted in amelioration of fever. Unfortunately, the patient died due to progression of underlying disease and multiorgan failure. However, this case report indicates a possible relevance of voriconazole-based treatment regimens in invasive S. prolificans infections.
