Clinical Image
A 58-year-old man with acute myeloid leukemia (AML) received allogeneic peripheral blood stem cell transplantation from his HLA-matched sister. After transplantation, he suffered grade II graft-versus-host disease (skin), and severe diarrhea probably due to intestinal thrombotic microangiopathy. Various immunosuppressive and antithrombotic therapies were performed for these symptoms. Three months later, he developed sepsis due to trichosporon species. As micafungin had been given since the time of preconditioning for transplantation as an antifungal prophylaxis, the agent was changed to liposomal amphotericin B. However, he died 3 days after that. On the day of his death, numerous fungi (Figure 1, Left) and fungal phagocytosis by neutrophils (Figure 1, Right) were found on his peripheral blood smear sample. This case was a breakthrough trichosporon fungemia [1], in a patient with AML receiving micafungin.
