Abstract(s)
Na presente dissertação, foi realizado um levantamento retrospetivo de características clínicas das lesões pigmentadas da mucosa oral. Estas podem ser desencadeadas por uma série de fatores locais e sistémicos, fisiológicos ou patológicos. A melanina é um pigmento granular endógeno que pode apresentar coloração que varia do amarelo ao preto.
As alterações ou distúrbios relacionados à melanina podem ser iniciados com trauma, infeção, hábitos (tabágicos e alimentares), uso de medicamentos e por alguns fatores sistémicos como a doença de Addison, síndrome de Peutz-Jeghers e tumores.
Esta revisão de literatura tem como objetivo discorrer sobre as principais lesões pigmentadas da cavidade oral, dando especial importância ao seu diagnóstico diferencial, já que esta abordagem implicará diretamente no estabelecimento do tratamento adequado a cada paciente.
In the present dissertation, a retrospective survey of the clinical characteristics of pigmented lesions of the oral mucosa was carried out. Pigmented lesions of the oral cavity may be dual to local, systemic, physiological or pathological factors. Melanin is an endogenous granular pigment that can exhibit coloration ranging from yellow to black. Changes or disorders related to melanin can be initiated with trauma, infection, habits (smoking, gums, food), use of medications and by some systemic factors such as Addison’s disease, Peutz-Jeghers syndrome and tumors. This literature review aims to discuss the main pigmented lesions of the oral cavity, giving special importance to their differential diagnosis, because this approach will directly imply the establishment of appropriate treatment for each patient.
