Late relapse following autologous bone marrow transplantation for acute myelogenous leukemia: case report and review of the literature.

Most relapses following autologous bone marrow transplantation (BMT) for acute myelogenous leukemia (AML) occur within 18 months. A patient is presented who relapsed 4 years after successful autologous BMT for AML. A review of the literature confirms this to be a rare event and may have been associated with extramedullary relapse of the leukemia.
