Fusarium is an opportunistic fungal pathogen which is emerging as a significant cause of morbidity and mortality in the immunocompromised host [Fleming RV, Walsh TJ, Anaissie EJ. Emerging and less common fungal pathogens. Infect Dis Clin North Am 2002;16:915-34]. This disease can be localized, focally invasive or disseminated, when two or more noncontiguous sites are involved. Therapeutic options are scarce and mortality reaches 80-90% in patients subjected to allogeneic hematopoietic stem cell transplant (allo-SCT) [Nucci M, Marr KA, Queiroz-Telles F, Martins CA, Trabasso P, Costa S, et al. Fusarium infection in hematopoietic stem cell transplant recipient. Clin Infect Dis 2004;1237-42]. We report a case of disseminated Fusariosis in a severe immunocompromised patient after allo-SCT that responded to treatment with the early combination of intravenous voriconazole and liposomal amphotericin B.
