    0.6-2.5/100,000 cases per year. [ 2 ] In hematology, essential thrombocythemia (ET) is a rare chronic blood cancer (myeloproliferative neoplasm) characterised by the overproduction of platelets (thrombocytes) by megakaryocytes in the bone marrow. [ 3 ] It may, albeit rarely, develop into acute myeloid leukemia or myelofibrosis. [ 3 ]

    en.wikipedia.org/wiki/Polycythemia_vera

    In oncology, polycythemia vera (PV) is an uncommon myeloproliferative neoplasm in which the bone marrow makes too many red blood cells. [1] The majority of cases [2] are caused by mutations in the JAK2 gene, most commonly resulting in a single amino acid change in its protein product from valine to phenylalanine at position 617.

  4. Thrombocythemia - Wikipedia

    en.wikipedia.org/wiki/Thrombocythemia

    In hematology, thrombocythemia is a condition of high platelet (thrombocyte) count in the blood. Normal count is in the range of 150 × 10 9 to 450 × 10 9 platelets per liter of blood, [1] but investigation is typically only considered if the upper limit exceeds 750 × 10 9 /L. When the cause is unknown, the term thrombocythemia is used, as ...

    en.wikipedia.org/wiki/Myeloproliferative_neoplasm

    Polycythemia vera (PV) is associated most often with the JAK2 V617F mutation greater than 95% of cases, whereas the remainder has a JAK2 exon 12 mutations. High hemoglobin or hematocrit counts are required, as is a bone marrow examination showing "prominent erythroid, granulocytic and megakaryocytic proliferation with pleomorphic, mature ...

  6. Giant platelet disorder - Wikipedia

    en.wikipedia.org/wiki/Giant_platelet_disorder

    Giant platelet disorders, also known as macrothrombocytopenia, are rare disorders featuring abnormally large platelets, thrombocytopenia and a tendency to bleeding. Giant platelets cannot stick adequately to injured blood vessel walls, resulting in abnormal bleeding when injured. Giant platelet disorder occurs for inherited diseases like ...

  7. Polycythemia - Wikipedia

    en.wikipedia.org/wiki/Polycythemia

    Polycythemia is defined as serum hematocrit (Hct) or hemoglobin (HgB) exceeding normal ranges expected for age and sex, typically Hct >49% in healthy adult men and >48% in women, or HgB >16.5 g/dL in men or >16.0 g/dL in women. [8] The definition is different for neonates and varies by age in children. [9][10]

    6947. Iron-deficiency anemia (or iron deficiency anaemia) is a common anemia that occurs when iron loss (often from intestinal bleeding or menses) occurs, and/or the dietary intake or absorption of iron is insufficient. In such a state, hemoglobin, which contains iron, cannot be formed. [5] Plummer–Vinson syndrome.

    en.wikipedia.org/wiki/Antiphospholipid_syndrome

    PAS stain. Antiphospholipid syndrome, or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by antiphospholipid antibodies. APS can lead to blood clots (thrombosis) in both arteries and veins, pregnancy-related complications, and other symptoms like low platelets, kidney disease, heart disease, and ...
