DONOR CELL LEUKEMIA DEVELOPING AFTER HEMATOPOIETIC STEM CELL TRANSPLANTATION FOR MULTIPLE MYELOMA

Abstract The development of secondary leukemia in donor cells after allogeneic stem cell transplantation is a rare event. We describe the occurrence of acute myeloid leukemia in donor cells 4 years after a stem cell transplantation for multiple myeloma. The multiple myeloma was relapsing at the time of the onset of acute myeloid leukemia. Secondary leukemia in donor cells after transplantation for multiple myeloma has not yet been reported.
