[Leukemic form of lymphosarcoma (clinical study of 7 cases]

Seven cases of leukaemic form of lymphosarcoma are presented. In all studied patients three characteristic signs were present: generalized lymphadenopathy, presence of lymphosarcoma cells in peripheral blood, spontaneous proliferation of white blood cells in short-term culture. Differential diagnostic difficulties with regard to chronic lymphatic leukaemia are stressed. It is thought that the sign of spontaneous proliferation may be used as a differential diagnostic criterion.
