RUIZ, Milton Artur; VASSALLO, José y SOUZA, Cármino Antonio de. Hematological abnormalities in patients chronically exposed to benzene. An update. Rev. Saúde Pública [online]. 1993, vol.27, n.2, pp. 145-151. ISSN 0034-8910. http://dx.doi.org/10.1590/S0034-89101993000200011.
A study was carried out into the hematological abnormabilities of peripheral blood bone marrow in patients chronically exposed to benzene. The metabolic biotransformation and the mechanisms involved in toxicity are described. Hematological data are described and discussed. Macrocytosis and lymphopenia are the earlieste hematological signs of benzene toxicity. Bone marrow abnormabilities are demostrated by the complementary methods of cytology and histology. Global hypocellularity was mainly due to the granulocytic series. Mastocytosis, eosinophilia and magakariocytic abnormalities are also presented. Inflamatory abnormalities and signs of dismyelopoiese could also be observed. The importance of peripheral blood abnormalities and the need for a critical approach to this important public health problem are emphasized.
