The lymphotropic virus of human T-cell I and II (HTLV-I/II) present genoma of ribonucleic acid (RNA) and generally infect CD4+ cell, with endemic frequency in some areas like Japan and Caribe with greater or minor predominancy in other places; in Brasilian Amazonia, the research is mainly connected to the native population. These virus are relationed with malign deseases, neurological disturbances and il11unodeficiencies, which cause viremia for long time without clinical effects. The HTLV is regarded as an ethiological agent of adult T-cell leukemia/lymphoma (L/LTA) and tropical spastic paraparesis / HTLV-I associated myelopathy (PET/HAM) among. This analisys has the mais purpose of researching the presence of HTLV and situate the most frequent (HTLV-I/II) in children with Acute Lymphoblastic Leukemia treated in the authorized Cancer Assistence in Belem, Para State, Brazil, observing the transmition way by lactation, the neurological symptoms with infections and its bibliografic revise. The rear search of virus was accomplish through the PCR (Polimerase Chain Reaction) tecnique that shows differences among HTLV-I and HTLV-II. Parameters among age, sex, skin lesions, progression and blood transfusion by porcentage had been remarked in a little girl, without relationship to transmition by breastfeeding, and there was no conection with HTLV as na ethiological agent of lymphoidal cells of neoplasia in childhood.
