A type of chronic leukemia in which the abnormal white blood cells appear to be covered with tiny hairs when viewed under a microscope.
An uncommon type of chronic lymphocytic leukemia. The leukemic cells are B lymphocytes that have characteristic "hair- like" projections when examined under the microscope. The spleen is frequently enlarged and the blood cell numbers are usually markedly decreased. The disease is very responsive to treatment with cladribine or pentostatin.
An uncommon new plasm of blood-forming tissues characterized by massively enlarged spleen, the presence in blood of specific malignant lymphoid cells with many fine projections on their surfaces, and a marked reduction in the number of red blood cells, granulocytes and platelets.
An unusual lymphocytic leukemia, usually B lymphocytes, characterized by a hair like appearance under pathologic inspection.
A form of chronic leukemia in which malignant B-lymphocytes (a type of white blood cell ) are seen in the bone marrow , spleen , and peripheral blood and when viewed under the microscope, these cells appear to be covered with tiny hair-like projections. Hairy cell leukemia represents 2% of all leukemia. See the entire definition of Hairy cell leukemia
A rare type of chronic leukemia usually found in middle-aged men. HCL rarely requires BMT as a treatment.
A rare form of leukemia related to chronic lymphocytic leukemia and characterized by the presence of abnormal cells with hair-like projections.
A rare type of leukemia in which abnormal B-lymphocytes (a type of white blood cell) are present in the bone marrow, spleen, and peripheral blood. When viewed under a microscope, these cells appear to be covered with tiny hair-like projections.
Hairy cell leukemia is a type of chronic lymphoid leukemia. It is uncommon, representing about 2% of all leukemias, or less than 1000 new cases diagnosed each year in the United States. Originally known as leukemic reticuloendotheliosis, hairy cell leukemia was first described by Bertha Bouroncle, M.D. and her colleagues at the Ohio State University College of Medicine in 1958.
