Resumo
Objetivos: Avaliar o risco de potencial maligno através da coloração com azul de toluidina e da classificação displásica das lesões verrucopapilares da cavidade oral (LVPO).
Materiais e métodos: Foram identificados pacientes com LVPO POVE localizados na cavidade oral nos quais foi aplicado azul de toluidina e posteriormente avaliadas as alterações displásicas para finalmente serem classificadas histopatologicamente como ausentes, baixo ou alto risco de transformação maligna. Os pacientes que recusaram a coloração com azul de toluidina AT, não aceitaram a biópsia excisional ou o tinha tecido insuficiente, presença de coilócitos ou dano citopático associado ao papilomavírus humano foram eliminados do estudo.
Resultados: Foram incluídos 34 pacientes com LVPO, dos quais 4 foram interpretados como tendo coloração positiva para azul de toluidina AT positiva, sendo 3 considerados intensos e 1 leve.
Conclusões: A LVPO pode emitir coloração positiva para azul de toluidina, bem como apresentar uma variedade heterogênea de alterações arquitetônicas e citológicas displásicas avaliadas histopatologicamente, que em todas as amostras, segundo o sistema binário, são classificadas como leve risco de transformação maligna.
