N\u00f3dulos palpebrais s\u00e3o comuns nos c\u00e3es, podendo frequentemente acometer todas as esp\u00e9cies. Animais de qualquer idade podem apresentar o aparecimento, bem como os c\u00e3es mais velhos s\u00e3o os mais acometidos e os gatos com menor frequ\u00eancia. As massas palpebrais se comportam em sua grande maioria de forma benigna, essas massas geralmente aumentam com o tempo, resultando em irrita\u00e7\u00e3o na superf\u00edcie ocular, altera\u00e7\u00f5es funcionais e estruturais nas p\u00e1lpebras. Quando o diagn\u00f3stico dessas massas palpebrais s\u00e3o malignas (uma pequena porcentagem), o tratamento sist\u00eamico adicional se torna necess\u00e1rio. Para prevenir autotrauma, ulcera\u00e7\u00f5es ou opacifica\u00e7\u00e3o e inflama\u00e7\u00e3o dos tecidos oculares adjacentes, \u00e9 importante a identifica\u00e7\u00e3o precoce de crescimento palpebrais anormais, bem como o tratamento completo e adequado.<\/p>\n

Tipos de massas palpebrais<\/h4>\n
\n
\nAdenomas, epiteliomas e adenocarcinomas tarsais<\/strong>: Essas massas s\u00e3o frequentemente observadas emergindo das margens palpebrais (em regi\u00e3o de gl\u00e2ndula de meibomio) ou da conjuntiva pr\u00f3ximas a elas. As gl\u00e2ndulas de meibomio secretam subst\u00e2ncias oleosas que ajudam a manter o filme lacrimal saud\u00e1vel, s\u00e3o gl\u00e2ndulas que revestem o interior das p\u00e1lpebras superior e inferior. As massas t\u00eam apar\u00eancias similares, podendo ser rosadas ou pigmentadas, multilobuladas e podem se tornar ulceradas e sangrarem. <\/div><\/div>\n
\nPapiloma<\/strong>: S\u00e3o massas que acometem mais os c\u00e3es jovens, tem sua origem viral nas p\u00e1lpebras e conjuntivas, nos c\u00e3es idosos podem aparecer como les\u00f5es isoladas. N\u00f3dulos de caracter\u00edsticas verrucosas, com aspecto acinzentado ou esbranqui\u00e7ado. Em gatos, os papilomas ocorrem raramente e se diagnosticados tendem a ser pedunculados e com \u00e1reas de alopecia perif\u00e9rica. Em c\u00e3es jovens tendem a ser autolimitantes.
\n<\/div><\/div>\n
\nCarcinoma de c\u00e9lulas escamosas<\/strong>: \u00c9 principalmente diagnosticado em gatos brancos ou com p\u00e1lpebras despigmentadas, sua ocorr\u00eancia est\u00e1 relacionada \u00e0 exposi\u00e7\u00e3o solar. Tendem a ser localmente invasivos, met\u00e1stase para linfonodos regionais s\u00e3o as mais observadas. As les\u00f5es podem ser ulcerativas e crostosas, juntamente com inflama\u00e7\u00e3o da p\u00e1lpebra e conjuntiva, formando uma \u00e1rea avermelhada e \u00famida.

As neoplasias palpebrais devem ser removidas precocemente, uma vez que ocorre o desconforto palpebral, irrita\u00e7\u00e3o e crescimento do mesmo. A escolha da terapia indicada deve ser baseada nas caracter\u00edsticas da neoplasia (evolu\u00e7\u00e3o do crescimento, invas\u00e3o local, malignidade, presen\u00e7a de met\u00e1stase). Os objetivos considerados nesta escolha s\u00e3o preservar a fun\u00e7\u00e3o e estrutura da p\u00e1lpebra. Grandes massas requerem anestesia geral para sua remo\u00e7\u00e3o. Ap\u00f3s a retirada, essas massas em quest\u00e3o devem ser submetidas ao histopatol\u00f3gico para obter um diagn\u00f3stico definitivo e determinar se h\u00e1 necessidade de uma terapia adicional ao tratamento.<\/p>\n","protected":false},"excerpt":{"rendered":"
