hairy cell leukaemiaA rare disease featuring overgrowth of B .LYMPHOCYTES usually in men between 40 and 60 years of age. The lymphocytes show prominent hair-like projections. There is a profound drop in the numbers of all blood cells and the spleen, which is the site of the bulk of the abnormal lymphocytes, is enlarged. Treatment is by spleen removal (splenectomy) and the use of drugs such as alpha-INTERFERON and deoxycoformycin.
