ABSTRACT

OBJECTIVE: To establish a connection between infection by the human papilloma virus (HPV) and development of malignant (squamous cell carcinoma) and benign lesions (epithelial hyperplasia papillomatosis and papilloma) of the oral cavity and oropharynx. METHOD: A retrospective study of 66 blades and paraffin blocks with biopsy tissue fixed with formalin. This material, collected in 2002, refers to a group of 44 men (66.7%) and 22 women (33.3%) with ages ranging from 11 to 100 years, with confirmed diagnoses of squamous cell carcinoma in 38 cases, of epithelial hyperplasia papillomatosis in 20 cases and of papillomas in 8 cases. This material was analyzed by immunohistochemistry and the presence of viral DNA in the biopsy samples was determined. RESULTS: Presence of the viral DNA (HPV) in 16 of the 38 cases of carcinoma (42.5%), 19 in 20 cases of hyperplasia (95%) and 8 in 8 cases of papilloma (100%) was detected. CONCLUSION: The samples in this study show the predominant incidence of the HPV in the epithelial hyperplasia papillomatosis and papilloma in relation to squamous cell carcinoma. This last lesion, on the other hand, did not show statistical correlation to the HPV.

ABSTRACT

O objetivo deste trabalho é estabelecer a relação entre a infecção pelo vírus do papiloma humano (HPV) e o desenvolvimento de lesões malignas (carcinoma epidermóide) e benignas (hiperplasia epitelial papilomatosa e papiloma) de cavidade bucal e orofaringe. MÉTODOS: Estudo retrospectivo de 66 lâminas e blocos de parafina com tecido biopsiado e fixado com formalina. Esse material, colhido no ano de 2002, refere-se a uma casuística de 44 homens (66,7 por cento) e 22 mulheres (33,3 por cento) com idades que variavam entre 11 e 100 anos. O diagnóstico foi confirmado em 38 casos de carcinoma epidermóide, 20 casos de hiperplasia epitelial papilomatosa e oito casos de papilomas. Utilizamos a imunohistoquímica para analisar este material e determinar a possível presença do DNA viral nas amostras citadas. RESULTADOS: Detectamos a presença do DNA viral (HPV) em 16 dos 38 casos de carcinoma (42,5 por cento), 19 em 20 casos de hiperplasia (95 por cento) e em todos os oito casos de papilomas (100 por cento). CONCLUSAO: Este estudo demonstrou que as lesões papilomatosas e hiperplásicas da boca e orofaringe estão associadas ao HPV, ao contrário do carcinoma espinocelular que não apresentou correlação estatística significante com este agente infeccioso.
