Hairy-cell leukaemia. False-colour transmission electron micrograph of abnormal B-lymphocytes isolated from the blood of a person suffering from hairy-cell leukaemia (HCL). The lymphocytes are covered with characteristic hair-like cytoplasmic projections. Leukaemia is a malignant disease in which the bone marrow & other blood-forming organs overproduce certain types of white blood cells. These immature or abnormal cells suppress the normal production of white and red cells,thereby increasing the sufferer's susceptibility to infection. Hairy-cell leukaemia is a rare form of leukaemia,most commonly occurring in young men. Magnification: x3100 at 6x4.5cm size | |
