Lusion, it’s important for clinical hematologists and hemato pathologists to be acquainted with CNL when approaching individuals with MPNs and persistent neutrophilia. A woman in her 40s who was incidentally identified to possess leukocytosis was referred towards the hematology service at the National Center for Cancer Care and Research for evaluation. Complete blood count revealed hyperleukocytosis with predominant neutrophilia. Peripheral blood and flow cytometry didn’t show any proof of Calcium Channel Inhibitor Compound lymphoproliferative disorder or myeloblasts. Bone marrow aspirate and biopsy revealed a hypercellular marrow with myeloid hyperplasia. Cytogenetics revealed normal karyotype. Tests for each Janus kinase mutation JAK2 V617F and rearrangement of the genes BCR-ABL1, plateletderived development factor receptora (PDGFRa), PDGFRb, and fibroblast growth element receptor1 (FGFR1) had been unfavorable. Thereafter, the diagnosis of CNL was reached. She was treated with pegylated interferon alpha2a, with extremely very good hematological response. Towards the best of our expertise, that is the first case of CNL reported amongst the Arab population.
