The common symptoms was fatigue,granulocytosis and upper abdominal discomfort or tumour. The splenomegaly was found in the majority of cases. The mature neutrophilic granulocyte in peripheral blood was high and cast longer time with raised segmented and band staged of neutrophils. Serum assay showed a raised level of VitB12 and uric acid. Bone marrow aspirate showed a hypercellular marrow with marked granulocytic proliferation, consisting mainly of stab forms and segmented neutrophils. The NAP score was high. Both Ph chromosome and bcr-abl fusion gene was negtive. Conclusion CNL was a scarce chronic leukemia. It should be discriminated with leukemoid reaction and chronic granulocytic leukemia.
