    2. Chronic Myeloproliferative Disorder
      1. hyper proliferation of neoplastic myeloid progenitor cells while retaining capacity for terminal differentiation
        JAK mutation
        polycythemia vera
        primary myelofibrosis
        Essential thrombocythemia
        Chronic Myeloid Leukemia
        Etiology
        more than 95% of patients with Philadelphia chromosome
        increase activity of tyrosine kinase due to formation of BCR-ABL complex
        escape from apoptosis
        less dependant on GF
        activation of RAS
        Treatment=tyrosine kinase inhibitor
        Imatinib
        Annual incidence= 1 to 2 cases per 100,00
        abrupt onset of pancytopenia
