The bone marrow histological picture was studied in 13 patients with hairy-cell leukemia (HCL) who were followed up at the Hematological Centre in the Latvian SSR. The diagnosis was made or proved in all the cases, among them in 9 patients - on the basis of the proliferation type of leukemia cells in the bone marrow trephine biopsy that is characteristic of HCL. The analysis of the clinical and morphological features of the disease has permitted the authors to distinguish specific types of HCL: 1) splenic and bone-marrow variants predominantly were diagnosed clinically, 2) typical and atypical variants resembling malignant lymphoma or chronic lymphoid leukemia were diagnosed histomorphologically. The authors have recommended trephine biopsy+ for a wider use (as a more informative method as compared to sternal punction) in the diagnosis and differential diagnosis of HCL.
Analysis of the disease course in 17 patients afflicted with hairy-cell leukemia enabled the authors to specify 3 clinico-hematologic variants of the disease: a typical or a splenic one (with a predominant injury to the spleen), an atypical or bone marrow one (with a predominant injury to bone marrow), and a hypoplastic one. The bone marrow variant was characterized by the most pronounced leukemic injuries to bone marrow, severe bacterial complications, and the most unfavourable prognosis. The remaining variants were marked by their own individual features and ran a more favourable course. The division of hairy-cell leukemia into 3 variants promotes the improvement of the disease diagnosis and the elaboration of the optimal treatment policy in each specific case as well as the disease prognosis. The pathogenetic heterogeneity of the hairy-cell leukemia variants is discussed.

We report on 12 patients who fulfilled the FAB diagnosis criteria of chronic myelomonocytic leukemia (CMML). Some clinical findings (splenomegaly) as well as biological parameters (WBC count, cellularity of bone marrow sections, presence of dyserythropoiesis in bone marrow smears) were subjected to particular analysis. This allowed the assignment of each patient onto one of three separate hematological syndromes: (1) RA or RAEB with monocytosis, (2) myelomonocytic dysplasia (a novel syndrome) and (3) true CMML. Such separation may have distinct prognostic significance and may, therefore, predict life expectancy.
