Resumo
Relatamos o caso de um homem de 45 anos com úlcera no palato há 10 dias. O paciente era usuário de álcool e tinha história de uso de cocaína há 17 anos, interrompida há 7 anos. Foi realizada biópsia incisional e os cortes histológicos revelaram extensa área ulcerada recoberta por membrana fibrinopurulenta, com pequenos ninhos
de células escamosas que apresentavam citoplasma
eosinofílico, nucléolos evidentes e por vezes múltiplos, atipias celulares discretas e diversas figuras mitóticas. As características clínicas e histológicas indicaram o diagnóstico de Sialometaplasia Necrotizante e o paciente
foi submetido a acompanhamento clínico. Na terceira semana de acompanhamento, a remissão da lesão tornou-
se evidente. Ressaltamos a importância do exame
histopatológico e imunohistoquímico no correto diagnóstico.
