[Rare forms of paraproteinemic hemoblastosis]

The paper is concerned with 10 cases of multiple myeloma with myeloid (myeloma-myeloid) splenomegaly and myelemia; 4 cases of chronic subleukemic (or aleukemic) lymphocyte plasma cell leukemia with paraproteinemia G which do not differ in the clinical or morphological picture from Waldenström's macroglobulinemia ("Waldenström's macroglobulinemia without macroglobulinemia"), and 2 cases of macroglobulinemia lymphocyte plasma cell lymphoma of the stomach and lymph nodes of the abdominal cavity with chronic plasma cell leukemia. The pathogenetic aspects of these rare forms of paraproteinemic hemoblastoses, problems of the diagnosis and treatment are discussed.
