  2. Bone marrow failure - Wikipedia

    en.wikipedia.org/wiki/Bone_marrow_failure

    Myelodysplastic syndrome (MDS) is a form of blood cancer in which the bone marrow no longer produces enough healthy, normal blood cells. [9] MDS are a frequently unrecognized and rare group of bone marrow failure disorders, yet the incidence rate has rose from 143 reported cases in 1973 to approximately 15,000 cases in the United States each year.

    Indicators of a poor prognosis: Advanced age; severe neutropenia or thrombocytopenia; high blast count in the bone marrow (20–29%) or blasts in the blood; Auer rods; absence of ringed sideroblasts; abnormal localization or immature granulocyte precursors in bone marrow section; completely or mostly abnormal karyotypes, or complex marrow ...

    en.wikipedia.org/wiki/Congenital_amegakaryocytic...

    Congenital amegakaryocytic thrombocytopenia (CAMT) is a rare autosomal recessive bone marrow failure syndrome characterized by severe thrombocytopenia, which can progress to aplastic anemia and leukemia. [4] CAMT usually manifests as thrombocytopenia in the initial month of life or in the fetal phase.

  5. Aplastic anemia - Wikipedia

    en.wikipedia.org/wiki/Aplastic_anemia

    Normal bone marrow has 30–70% blood stem cells, but in aplastic anemia, these cells are mostly gone and are replaced by fat. [ 5 ] [ 6 ] First-line treatment for aplastic anemia consists of immunosuppressive drugs —typically either anti-lymphocyte globulin or anti-thymocyte globulin —combined with corticosteroids , chemotherapy , and ...

  6. Chronic lymphocytic leukemia - Wikipedia

    en.wikipedia.org/wiki/Chronic_lymphocytic_leukemia

    Chronic lymphocytic leukemia (CLL) is a type of cancer that affects the blood and bone marrow. [8] [9] In CLL, the bone marrow makes too many lymphocytes, which are a type of white blood cell. [8] [9] In patients with CLL, B cell lymphocytes can begin to collect in their blood, spleen, lymph nodes, and bone marrow.

  7. List of hematologic conditions - Wikipedia

    Sideroblastic anemia or sideroachrestic anemia is a disease in which the bone marrow produces ringed sideroblasts rather than healthy red blood cells (erythrocytes). [58] It may be caused either by a genetic disorder or indirectly as part of myelodysplastic syndrome. [59] Southeast Asian ovalocytosis: D58.1: 9416

  8. Acute myeloid leukemia - Wikipedia

    en.wikipedia.org/wiki/Acute_myeloid_leukemia

    The underlying mechanism involves replacement of normal bone marrow with leukemia cells, which results in a drop in red blood cells, platelets, and normal white blood cells. [1] Diagnosis is generally based on bone marrow aspiration and specific blood tests. [3] AML has several subtypes for which treatments and outcomes may vary. [1]

  9. Essential thrombocythemia - Wikipedia

    en.wikipedia.org/wiki/Essential_thrombocythemia

    The JAK 2 gene signals a protein that promotes the growth of cells. The protein is part of a signaling pathway called the JAK/STAT pathway. The JAK2 protein controls the production of blood cells from hematopoietic stem cells which are located in the bone marrow and can eventually become platelets, red blood cells or white blood cells.
