Megakaryocytes presented with moderate pleomorphism, most cells showing nuclear hyposegmentation with normal nuclear to cytoplasmic ratio (a) and a few
myeloproliferative hypersegmented and atypical forms.

However, dysplastic features previously reported in primary hematologic diseases were also revealed in peripheral blood smears: (1) a neutrophil with a closed-loop nucleus, a dysplastic feature reported in
myeloproliferative neoplasm [10] (Figure 2D), (2) nuclear projections previously reported in androgen-expressing tumors [11] (Figure 2E), (3) hypersegmented nuclei, a common finding in vitamin B12 or folic acid deficiency (Figure 2F), (4) pseudo-PHA referring to neutrophils with mono- and bilobed nuclei [6, 7] (Figures 2G and 2H), and (5) karyorrhexis, which is a rare finding of dysgranulopoiesis as discussed earlier [5] (Figure 2I).
Atypical chronic myeloid leukemia (aCML), a rare disorder of hematopoietic stem cells, has both myelodysplastic and
myeloproliferative characteristics and is classified as an example of myelodysplastic/myeloproliferative neoplasms (MDS/MPN) according to the World Health Organization (WHO) classification system (1).
Sequencing identified an in-frame fusion of exon 17 of ZNF198 to exon 9 of FGFR1 [Figure 1]e, which was indicative of 8p11
myeloproliferative syndrome (EMS, World Health Organization [WHO] 2008, myeloid and lymphoid neoplasms with FGFR1 abnormalities [sup][1] ).
Myeloproliferative neoplasms (MPNs) are a heterogeneous group of disorders manifested by increased hematopoiesis and proliferation of one or more of the hematologic cell lines.
Among the topics are principles of flow cytometry, limitations, acute leukaemia, myelodysplastic syndromes and
myeloproliferative neoplasms, minimal residual disease, and reactive and non-neoplastic phenomena.

Its lead product is CYT387, an orally administered inhibitor of both the JAK1 and JAK2 kinases, which have been implicated in a number of hematological and immune cell disorders including

Myeloproliferative neoplasms (MPNs) (6) are a group of hematologic malignancies that include polycythemia vera (PV), essential thrombocythemia (ET), and primary myelofibrosis (PMF).
Evidence was seen for pleiotropic relationships, notably correlations for chronic lymphocytic leukemia with elevated familial risk of other B cell tumors and
myeloproliferative neoplasms.
