Chronic myeloproliferative neoplasms (CMPN) are a group of hematopoietic stem cell disorders associated with abnormal blood cell production and bone marrow (BM) morphology. Myeloid cells from the majority of patients with polycythaemia vera (PV) and approximately half of those with essential thrombocythaemia (ET) and primary myelofibrosis (PMF) carry the JAK2V617F mutation.1–3 Recent proposed revisions to the World Health Organization (WHO) diagnostic criteria for these disorders include the presence of JAK2V617F mutation as a major criterion for diagnosis.4 Although various studies have shown that JAK2 mutation testing can be successfully performed on peripheral blood (PB),1–3 bone marrow aspirate (BMA),5 or BM biopsy,6 7 comparison …
