essential thrombocythemia is a rare myeloproliferative disorder in pediatrics. this myeloproliferative disorder is charactherized by thrombocytosis and hyperplasia of megakaryocytes in the bone marrow. other cell lines are not involved.jak2v617fmutations has been identified in approximately half the patients with this disorder. we describe a 12-year-old boy with essential throbocythemia. the pa...

Transient myeloproliferative disorder is a hematological condition observed during the neonatal period in patients with Down syndrome [1]. This disorder mimics congenital leukemia and the blast cells were often reported to show characteristics compatible with those of megakaryoblasts [2] or pluripotent stem cells [3]. Although this disorder usually resolves gradually without antileukemic treatm...

Children with Down's syndrome are at an increased risk for development of several hematological disorders like acute leukemia, acute myelofibrosis of childhood and transient myeloproliferative disorder (TMD)(1). Transient myeloproliferative disorder is recognized shortly after birth or in neonatal period and is characterized by leukocytosis and thrombocytopenia, which resolves spontaneously in ...

conclusions both the cases discussed in our study have inv(9) as the sole abnormality and are found to confer a relatively poor prognosis. case presentation we present the case of a chronic myeloid leukemia (cml) patient who showed intermittent relapse on treatment, with a rare appearance of clones with dual inversion (9) breakpoints [inv(9)(p22q34); inv(9)(p11q21)]. we also present the first r...

Two patients with cerebral venous thrombosis are described. In both patients laboratory findings suggested an underlying haematological disorder and bone marrow biopsy showed a myeloproliferative disorder. Both chronic cerebral venous thrombosis and early myeloproliferative disorders are difficult to diagnose. Their combined occurrence may be less rare than is frequently supposed.
