Chronic myeloid leukemia (CML) is a clonal malignant hematopoietic disorder that arises in a hematopoietic stem cell. Its characteristic cytogenetic abnormality is an abnormal chromosome 22 called the Philadelphia (Ph) chromosome. The BCR ‐ ABL1 fusion gene in this chromosome can encode a tyrosine protein kinase and is the molecular basis of CML pathogenesis. The tyrosine kinase inhibitor (TKI) imatinib is the ‘gold standard’ therapy for the treatment of CML. However, around 30% of the patients develop imatinib resistance. In this report, we will illustrate a case of an adult female with acute transformation of CML whose imatinib resistance was reversed by nilotinib and has had a long‐term survival.
