Acute lymphoblastic leukemia (ALL) is a cancer of the lymphoid line of blood cells characterized by the development of large numbers of immature lymphocytes. [1] Symptoms may include feeling tired, pale skin color, fever, easy bleeding or bruising, enlarged lymph nodes, or bone pain. [1]
Precursor B-cell lymphoblastic leukemia is a form of lymphoid leukemia in which too many B-cell lymphoblasts (immature white blood cells) are found in the blood and bone marrow. It is the most common type of acute lymphoblastic leukemia (ALL). It is sometimes additionally classified as a lymphoma, as designated leukemia/lymphoma. ALL is the ...
A B-cell leukemia is any of several types of lymphoid leukemia which affect B cells. [1] Types include (with ICD-O code): [citation needed] 9823/3 - B-cell chronic lymphocytic leukemia/small lymphocytic lymphoma; 9826/3 - Acute lymphoblastic leukemia, mature B-cell type; 9833/3 - B-cell prolymphocytic leukemia; 9835/3-9836/3 - Precursor B ...
Lymphoproliferative disorders are a set of disorders characterized by the abnormal proliferation of lymphocytes into a monoclonal lymphocytosis. The two major types of lymphocytes are B cells and T cells, which are derived from pluripotent hematopoietic stem cells in the bone marrow.
B-cell chronic lymphocytic leukemia (ICD-O: 9823/3) 30% of all leukemias. Also 3 to 4% of lymphomas in adults [1] Small resting lymphocytes mixed with variable number of large activated cells. Lymph nodes are diffusely effaced [1] CD5, surface immunoglobulin [1] Occurs in older adults. Usually involves lymph nodes, bone marrow and spleen.
In adults, absolute lymphocytosis is present when the lymphocyte count is greater than 5000 per microliter (5.0 x 10 9 /L), in older children greater than 7000 per microliter and in infants greater than 9000 per microliter. [1] Lymphocytes normally represent 20% to 40% of circulating white blood cells. When the percentage of lymphocytes exceeds ...
Acute lymphoblastic leukemia (ALL) 4.0% Acute myeloid leukemia (AML) 8.7% Chronic lymphocytic leukemia (CLL) sorted under lymphomas according to current WHO classification; called small lymphocytic lymphoma (SLL) when leukemic cells are absent. 10.2% Chronic myelogenous leukemia (CML) 3.7% Acute monocytic leukemia (AMoL) 0.7% Other leukemias 3.1%
Acute leukemia or acute leukaemia is a family of serious medical conditions relating to an original diagnosis of leukemia. In most cases, these can be classified according to the lineage, myeloid or lymphoid , of the malignant cells that grow uncontrolled, but some are mixed and for those such an assignment is not possible.
