Therapy-related acute myelogenous leukemia (t-AML) is a generally fatal disease with a very poor response to conventional chemotherapy. Allogeneic stem cell transplantation (allo-SCT) has been reported in patients with chemotherapy-responsive t-AML. However its use is limited owing to complications from previous treatments. Nonmyeloablative conditioning provides rapid hematologic engraftment and it is a feasible option for patients who are at increased risk for conventional SCT. There are few data on their use in patients with t-AML. We describe the case of a boy who developed visceral fungal infection with liver abscesses after induction chemotherapy for t-AML. He received allo-SCT with a nonmyeloablative regimen, plus amphotericin B during the transplant procedure. The patient is alive and free of both leukemia and fungal infection 2 years after allo-SCT. Nonmyeloablative allo-SCT may provide durable remission in patients with t-AML, preexisting invasive fungal infections, and a high risk of adverse effects from standard chemotherapy and prolonged cytopenia, without resurgence of the fungal infection.
