Differentiation between chronic lymphocytic leukaemia (B-CLL) and non-Hodgkin lymphomas in the leukaemic phase by the mouse red blood cell rosette assay.
A distinction between B-CLL and other malignant B-cell lymphomas in the leukaemic phase may be difficult. Mouse red blood cell rosette formation of lymphocytes from 97 patients with B-CLL and 19 patients suffering from other B-cell lymphoproliferative disorders was examined together with lymphocyte rosette formation of healthy controls. The majority of circulating lymphocytes of B-CLL patients formed rosettes with mouse red cells, whereas there was no relationship between the number of peripheral neoplastic B-cells and that of rosette forming cells in other lymphoproliferative diseases. The relatively simple mouse red blood cell rosette assay proved to be of value in the differentiation of otherwise nearly related conditions.
