title: [Differential diagnosis of acute leukemia and hematosarcoma in children].
abstract: Comparative analysis of hemopoiesis and study of the morphofunctional characteristics of blast cells in 89 children with hematosarcomas and in 152 children afflicted with acute leukemia revealed significant differences both in the nature of blast metaplasia of bone marrow and in the degree of inhibiting erythro- and thrombocytopoiesis in acute leukemias and hematosarcomas in the stage of leukemization. Study of the function of blast cells allowed one to distinguish specific features of tumor elements similar in their cytological parameters. The differences in the character of hemopoiesis derangement in different forms of hemoblastoses can be used under clinical conditions for differential diagnosis of the leukemic stage of hematosarcomas and leukemias.
