B-cell prolymphocytic leukemia, referred to as B-PLL, is a rare blood cancer.It is a more aggressive, but still treatable, form of leukemia.. Specifically, B-PLL is a prolymphocytic leukemia (PLL) that affects prolymphocytes – immature forms of B-lymphocytes and T-lymphocytes – in the peripheral blood, bone marrow, and spleen.
Prolymphocytic leukemia is divided into two types according to the kind of cell involved: B-cell prolymphocytic leukemia and T-cell prolymphocytic leukemia. It is usually classified as a kind of chronic lymphocytic leukemia .
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 ...
B cell prolymphocytic leukemia, a related, but more aggressive disorder, has cells with similar phenotype, but are significantly larger than normal lymphocytes and have a prominent nucleolus. The distinction is important as the prognosis and therapy differ from CLL.
B-cells form in the bone marrow and undergo gene rearrangement in order to develop B-cell receptors (BCRs) that bind to a specific antigen. Once activated by an antigen, B-cells proliferate and further differentiate into plasma cells and memory B-cells. [4] B-cells that have not encountered an antigen are called naive B cells.
Sarcoma: Cancers arising from connective tissue (i.e. bone, cartilage, fat, nerve), each of which develop from cells originating in mesenchymal cells outside of the bone marrow. Lymphoma and leukemia : These two classes of cancer arise from immature cells that originate in the bone marrow, and are intended to fully differentiate and mature into ...
The B-cell lymphomas are types of lymphoma affecting B cells. Lymphomas are "blood cancers" in the lymph nodes . They develop more frequently in older adults and in immunocompromised individuals.
B-cell chronic lymphocytic leukemia (also known as small cell lymphocytic lymphoma) is a blood cancer that involves the B-cell lymphocytes; responsible for the creation of antibodies. Of the two general types of chronic lymphocytic leukemias (the other involving T-cells), B-cell chronic lymphocytic leukemia accounts for approximately 95 percent ...
