[Clinical application of the international histological and cytological classification of hematologic and lymphatic neoplasms].

The first part of the International classification of neoplastic diseases of haemopoietic and lymphatic tissues by Mathé et al is discussed. The classification is exhaustive but the Table does not include all varieties of hemoblastoses mentioned in the explanatory text and shown in illustrations. Some of the terms seem disputable or inaccurate. The structure of leukemias (623 cases) based on the data of the Sverdlovsk regional haematological centre for 1975-1979 is presented, as reconsidered according to the above classification. The role of trepanobiopsies in diagnosis of leukemias is emphasized.
