Hairy Cell Leukemia - A rare type of chronic lymphoid leukemia, hairy cell leukemia (HCL) is characterized by the appearance of abnormal white blood cells (B-lymphocytes) in the spleen, bone marrow, and peripheral blood (the blood that circulates in the body). The name "hairy cell" comes from the appearance of tiny, fibrous, hair-like projections extending from the abnormal cells (when viewed under a microscope). Hairy cell leukemia occurs more often in middle-aged men than in women, and is not found in children or teenagers.
