A Disseminated Fusarium fujikuroi Species Complex Infection Prior to Allogeneic Hematopoietic Stem Cell Transplantation.

A 53-year-old man was diagnosed with acute myeloid leukemia, which was refractory to chemotherapies. Systemic papules appeared afterward. The skin biopsies revealed filamentous fungal infection including fusariosis. Despite antifungal therapy, the infection did not resolve, because neutropenia persisted with the leukemia. He underwent hematopoietic stem cell transplantation (HSCT) to overcome the leukemia and restore normal hematopoiesis but died from fusariosis just before engraftment. Fusarium fujikuroi species complex was detected in blood cultures with poor antifungal susceptibility. Because restoring normal hematopoiesis is important in the treatment of fusariosis, HSCT might be considered for patients with persistent pancytopenia.
