What is Hairy Cell Leukemia? Hairy cell leukemia is a chronic and rare form of adult leukemia. It is estimated that approximately 2% of adult patients with leukemia have this form of disease. While the cause of this malignancy is not known, the origin of the malignant cell is thought to develop from the memory B cell compartment

Hairy cell leukemia cells, which appear as the darker cells in this photo, are surrounded by a halo of fine projections (villi). To diagnose hairy cell leukemia, your doctor may take a sample of bone marrow from your body and examine it under a microscope to look for hairy cells Hairy cell leukemia is a malignancy with a variable course that can be relatively indolent or rapidly fatal. Alterations in the immune system are responsible for much of the morbidity and mortality from hairy cell leukemia. More than 60% of patients die from infection, and infections are both pyogen Diagnosis. In addition to the B-cell antigens CD19, CD20, and CD22, the cells coexpress CD11c, CD25, and CD103. The BRAF-V600E mutation is a hairy cell leukemia-defining genetic lesion that can be used diagnostically.[1,2] The decision to treat is based on symptomatic cytopenias, massive splenomegaly, or the presence of other complications.About 10% of all patients will never require therapy Classic hairy cell leukemia (HCL) is a rare mature B-cell malignancy associated with pancytopenia and infectious complications due to progressive infiltration of the bone marrow and spleen.

  2. Hairy cell leukemia is a rare, slowly growing blood cancer that affects about 950 Americans each year. The cancer is in the B cells (lymphocytes), a type of white blood cell that fights infection. Affected cells look hairy due to protrusions of cytoplasm that give the cells a ruffled outside border
  3. Hairy cell leukemia is a mature B cell neoplasm. It is usually classified as a sub-type of chronic lymphoid leukemia (CLL) for convenience. It is uncommon, representing about 2% of all leukemias, or less than a total of 2000 new cases diagnosed each year in North America and Western Europe combined
  4. The genetic cause of hairy cell leukemia is through the abnormal activation of a signaling pathway called RAF-MEK-ERK. This pathway becomes activated through a mutation called BRAF-V600E, which has been characterized and can be detected in genetic studies. As a result of this mutation, B-cells stop undergoing apoptosis (programmed cellular death), adopt a hairy pattern, and replicates excessively
  5. Hairy cell leukemia (HCL) is a chronic lymphoproliferative disorder characterized as a mature B-cell malignancy based on the expression of CD19, surface immunoglobulin, and the clonal rearrangement of immunoglobulin heavy and light chain genes
