Abstract
161 cases of CML have been studied. Clinically significant adenopathies were present in 3,2% of the patients at the moment of diagnosis, and in the subsequent course they appeared in 7% of them. The behaviour of adenopathies showed to be unrelated to: --splenomegaly; --blastic metamorphosis in the peripheral blood or in the marrow (which they often preceded from 3 to 26 months); --hematological sensibility to cytostatic therapy; and furthermore they often acted as the most important clinical and therapeutic problem. From the cyto-histological point of view three features have been observed: 1) blastic metamorphosis in a lymphnode showing features of myeloid metaplasia; 2) blastic invasion in a lymphnode without any sign of myeloid metaplasia; 3) malignant lymphoma. Cytological examination of imprints and ultrastructural studies, besides the usual histological investigations, proved to be useful for the definition of the above mentioned features. In lymphomatous forms, together with the study of the cariotype and the research of the Ph' chromosome, the performance of immunocytological investigations is also necessary.
