Além da associação com algumas doenças benignas, tais como mononucleose infecciosa, leucoplasia pilosa e doença linfoproliferativa pós-transplante, o EBV também tem sido associado a diversas neoplasias como linfoma de Burkitt, Doença de Hodgkin, carcinoma de nasofaringe, carcinoma gástrico, entre outros. Nas células tumorais, o referido vírus se apresenta no estado latente, podendo expressar alguns dos treze genes latentes, dependendo do tecido e do estado imunológico do hospedeiro. Apesar da vasta literatura acerca dos expressos latentes, os mecanismos envolvidos na oncogênese dos diversos tecidos ainda não estão totalmente esclarecidos. Nesse cenário, o presente artigo faz uma revisão acerca dos expressos latentes do EBV, abordando os padrões de latência observados nos cânceres associados, características estruturais e os efeitos descritos para cada expresso, com enfoque no papel oncogênico.</span></p>
