Chronic myeloid leukemia (CML) is a clonal myeloproliferative disorder, which can involve the hematopoietic stem cell or early progenitor cells, without the loss of their capacity to differenti-ate. Typically, CML has three clinical phases: a chronic phase, an accelerated phase, and an aggressive transformation in blast crisis, analogous to acute leukemia. The following article presents the case of a 49-year-old patient diagnosed with Philadelphia-negative CML in blas-tic transformation, where after multiple conventional acute leukemia induction chemotherapy regimens an unrelated allogeneic hematopoietic stem cell transplant was performed.
