[Chronic lymphocytic leukemia. II. Differentiation of various forms of chronic lymphocytic leukemia by cytological and immunological indicators].

The authors present their studies on the cytologic and some immunologic features of leukemic cells which determine the specificity of lymphocyte population in the various forms of lymphatic leukemia. 133 patients who were treated in their clinic for the period 1980-1984 were studied. Four clinical forms were differentiated which had been published elsewhere.
