The objective of this study was to describe the cytological and immunophenotypical parameters evocative of B-cell Chronic Lymphocytic Leukaemia (B-CLL) and their ability to participate to the differential diagnosis of other B-chronic lymphoproliferatives disorders with blood dissemination (B-CLD). Two groups of pathology included 92 patients, 79 patients had a B-CLL and the 13 other had a B-CLD (1 Prolymphocytic Leukaemia, 12 non- Hodgkin's Lymphoma in which 4 Splenic Lymphoma with Villous Lymphocytes or SLVL). The lymphoid morphology was studied on blood smear stained with May Gr nwald Giemsa and the immunophenotypical analysis was performed by flow cytometry. The 72 patients with B-CLL were characterized by a predominance of small mature lymphocytes with a Matutes's CLL score 3 (generally CD5+, CD23+, SmIg poor expression). 4 out of B-CLL with cleaved lymphocytes 5 % showed the same immunological characteristics than the typical B-CLL cases. 3 cases of B-CLL with prolymphocytes between 5 and 55 % showed in 2 cases an immunophenotyping compatible with the diagnosis of B-CLD. The presence of shadow cells of Gumprecht was highly evocative of B-CLL. In conclusion, the cytological analysis remains at the root of any diagnosis and can be sufficient in most cases of typical CLL with the presence of shadow cells of Gumprecht on the blood smear. In case of presence of cleaved lymphocytes, the immunophenotyping becomes essential to confirme the diagnosis of B-CLL. In prolymphocytic cases, the differential diagnosis between mixed CLL and B-CLD (especially Mantle Cell Lymphoma and Marginal Zone B-Cell Lymphoma without villous lymphocytes) needs a multidisciplinary approach (clinical, cytogenetical and histological).

Splenic lymphoma with circulating villous lymphocytes (SLVL) is a special kind of lymphoproliferative disease characterized by specific clinical, haematological, histomorphological and immunophenotypic features that make it different from hairy cell leukaemia, prolymphocytic leukaemia and non-Hodgkin lymphoma. Four patients suffering from SLVL, 3 men and 1 woman, 62 years in average (range 55-67 years), are presented. All patients had anaemia and splenomegaly. One patient had huge pseudocyst of the spleen, two had mild lymph-adenopathy, while 3 patients had thrombocytopenia. The number of WBC ranged from 13-29 x 10(9)/l with lymphocytes ranging from 62-80%. Monoclonal IgM paraprotein was found in 3 patients. Immunophenotyping showed cells with features of mature B lymphocytes. Splenectomy was carried out in three patients. They all recovered and stayed symptomfree. One patient refused surgery. In our opinion SLVL is not a rare disease as it was thought; it should especially be taken into diagnostic consideration in elder patients, particularly in males with splenomegaly and lymphocytosis.
