MELANOMA ORAL: O QUE O DENTISTA PRECISA SABER?
Conteúdo do artigo principal
Resumo
O melanoma oral é uma neoplasia maligna de melanócitos, caracterizada por um comportamento agressivo e prognóstico extremamente reservado. Melanomas na cavidade oral são raros e geralmente são diagnosticados em estágio avançado, reduzindo a sobrevida dos pacientes. O objetivo desta revisão narrativa de literatura é compilar os aspectos essenciais do melanoma oral e demais pigmentações para orientar o diagnóstico precoce pelo cirurgião-dentista. Realizou-se uma pesquisa nas bases de dados Pubmed, Embase, Lilacs e Cochrane. O melanoma oral apresenta-se como uma mácula ou nódulo, de coloração castanha ou preta, podendo demonstrar variações na cor e até mesmo despigmentações. Ele tem predileção pelo palato e pela gengiva maxilar, usualmente é assintomático, e aparenta acometer ligeiramente mais o sexo masculino, especialmente entre a 4ª e 7ª décadas de vida. Apesar de possuir características clínicas similares com o melanoma cutâneo, são consideradas variantes distintas. O cirurgião-dentista deve conhecer as principais características clínicas do melanoma oral e demais pigmentações da cavidade oral a fim de realizar o diagnóstico precoce da neoplasia e conduzir o caso adequadamente.
