Myeloid/NK cell leukemia is distinct entity, being different from the myeloid/NK cell precursor acute leukemia and blastic NK cell lymphoma/leukemia in morphology and immunotypes. The entity is a more mature state than the latter. We reported a typical case with presentation, immunology and cytogenetic results. The patient went to see a doctor with leucocytosis, anemia and thrombocytopenia. There are no superficial lymph nodes and splenohepatomegaly. The morphology of leukemia cells in bone marrow was similar to that of acute promyelocytic leukemia. The leukemia cells express CD13, CD33, CD15, and CD56, not expressing CD34, HLA-DR and CD16. No abnormal cytogenetics were found. The patients were given chemotherapy as acute myeloid leukemia, and got complete remission.
