The aim of the study was to demonstrate the relevance of immunophenotyping by flow cytometry in patients with prolonged lymphocytosis and / or cytomorphological changes compatible with lymphoproliferative diseases. In this study 460 patients (244 men and 216 women) with DLPC were evaluated. Were analyzed by flow cytometry with a panel of monoclonal antibodies consisting of CD3, CD4, CD5, CD8, CD10, CD19, CD22, CD23, CD25, CD38, CD45, CD16/CD56, and HLADR heavy and light chains of immunoglobulins. It also examines information regarding age, gender of patients and laboratory data as leucocytes, cytomorphological analysis, platelet count and hemoglobin determination. The results showed 398 cases of chronic lymphoproliferative disorders and 62 of DLPC B cell lymphoproliferative diseases T. B showed the following distribution : 253 cases of chronic lymphocytic leukemia (CLL), 42 cases of multiple myeloma ( MM ), 37 cases of lymphoma non - Hodgkin lymphoma in leukemic phase (NHL) , 17 cases of pro- B lymphocytic leukemia ( B -PLL), 15 cases of mantle cell lymphoma (MCL ), 12 cases of plasma cell leukemia ( PCL), 9 cases of lymphoma Burkitt (Linf B), 8 cases of leukemia villous cells ( LCV), 3 cases of splenic lymphoma with villous cells (LECV), a case of follicular lymphoma (LF) and a Waldenstr?n macroglobulinemia ( MW). The diseases source NK / T were 23 cases of peripheral T cell lymphoma (LCTP), 14 cases of T prolymphocytic leukemia (T -PLL), 10 cases of leukemia T of large granular lymphocytes (LGL -T) 9 cases of leukemia cells of adult T (LCTA), 5 cases of Sezary syndrome (SS) and a case of large granular NK leukemia (LGL -NK) lymphocytes. In conclusion, the combined use of the monoclonal antibody panel careful cytomorphological analysis was shown to be essential in immune diagnosis and classification of chronic lymphoproliferative disorders. This study was approved by the IRB - HUOL under number 356 / 09 / Os transtornos linfoproliferativos cr?nicos (DLPC) s?o doen?as do sistema linfoide caracterizadas pela prolifera??o anormal de linf?citos maduros que acometem c?lulas B, linf?citos T e c?lulas NK. O objetivo do estudo foi demonstrar a relev?ncia da imunofenotipagem por citometria de fluxo em pacientes portadores de linfocitose prolongada e/ou altera??es citomorfol?gicas compat?veis com doen?as linfoproliferativas. Neste estudo foram avaliados 460 pacientes (244 homens e 216 mulheres) com DLPC. Foram analisados por citometria de fluxo com um painel de anticorpos monoclonais constitu?do por CD3, CD4, CD5, CD8, CD10, CD19, CD22, CD23, CD25, CD38, CD45, CD16/CD56, HLADR e cadeias leves e pesadas de imunoglobulinas. Foram tamb?m investigadas informa??es referentes ? idade, ao g?nero dos pacientes e aos dados laboratoriais como: leucometria, an?lise citomorfol?gica, contagem de plaquetas e determina??o da hemoglobina. Os resultados demonstraram 398 casos de doen?as linfoproliferativas cr?nicas B e 62 de DLPC de c?lula T. As doen?as linfoproliferativas B apresentaram a seguinte distribui??o: 253 casos de leucemia linfoc?tica cr?nica (LLC), 42 casos de mieloma m?ltiplo (MM), 37 casos de linfoma n?o Hodgkin em fase leuc?mica (LNH), 17 casos de leucemia pr?-linfoc?tica B (LPL-B), 15 casos de linfoma de c?lulas do manto (LCM), 12 casos de leucemia de c?lulas plasm?ticas (LCP), 9 casos de linfoma de Burkitt (Linf B), 8 casos de leucemia de c?lulas vilosas (LCV), 3 casos de linfoma espl?nico de c?lulas vilosas (LECV), um caso de linfoma folicular (LF) e um de macroglobulinemia de Waldenstr?n (MW). As doen?as de origem T/NK foram: 23 casos de linfoma de c?lulas T perif?ricas (LCTP), 14 casos de leucemia pr?linfoc?tica T (LPL-T), 10 casos de leucemia de grandes linf?citos T granulares (LGLT), 9 casos de leucemia de c?lulas T do adulto (LCTA), 5 casos de S?ndrome de Sezary (SS) e um caso de leucemia de grandes linf?citos NK granulares (LGL-NK). Em conclus?o, o uso do painel de anticorpos monoclonais combinado ? an?lise citomorfol?gica cuidadosa mostrou-se essencial no diagn?stico e classifica??o imune das doen?as linfoproliferativas cr?nicas. O presente estudo foi aprovado pelo CEP HUOL sob n?mero 356/09
