Resumo
As lesões estomatológicas apresentam uma elevada frequência no gato, contudo a inespecificidade dos sinais clínicos e as semelhanças macroscópicas entre as diferentes lesões dificultam o seu diagnóstico, pelo que são muitas vezes subdiagnosticadas. Este trabalho teve como objetivo realizar um estudo retrospetivo das doenças orais observadas em gatos, com base no arquivo do Laboratório de Histologia e Anatomia Patológica da UTAD, de forma a poder determinar a sua frequência e características.
A amostra estudada foi constituída por 207 relatórios histopatológicos de biopsias orais felinas dos quais foram registados e avaliados parâmetros clínicos, nomeadamente o sexo, a idade e a raça. As lesões de natureza inflamatória foram predominantes, correspondendo a 76% das amostras analisadas. A gengivoestomatite crónica felina (55,6%), a estomatite (5,8%) e o complexo eosinofílico felino (4,8%) foram as doenças inflamatórias mais observadas. Relativamente às lesões neoplásicas, embora que menos frequentes (24% do total avaliado), foi possível determinar o carcinoma pavimentocelular (8,2%) e o fibrossarcoma (6,7%) como os tumores da cavidade oral mais diagnosticados.
Este trabalho permitiu concluir que, na cavidade oral do gato, as lesões inflamatórias são mais comuns do que as neoplásicas, e que a gengivoestomatite crónica felina é a lesão estomatológica mais frequente nesta espécie.
Oral cavity lesions are highly common in the cat, however, the unspecific clinical signs and the macroscopic similarity between the different lesions complicate their diagnosis, which is why oral cavity lesions are often underdiagnosed. This work aimed to perform a retrospective study comprising feline oral cavity lesions, based on the histopathological records from the UTAD’s Laboratory of Histology and Anatomical Pathology, to describe their frequency and characteristics. The sample studied was constituted of 207 histopathological reports of feline oral biopsies. In each one of the biopsies clinical parameters, specifically sex, age and race were registered and evaluated. Inflammatory lesions were predominant, accounting for 76% of all the analyzed samples. Feline chronic gingivostomatitis (55.6%), stomatitis (5.8%), and the feline eosinophilic complex (4.8%) were the most inflammatory diseases observed. Regarding the neoplastic lesions, although they were less frequent (24%), it was possible to determine squamous cell carcinoma (8.2%) and fibrosarcoma (6.7%) as the most diagnosed oral cavity tumors. This work concluded that in the cat’s oral cavity, inflammatory lesions are more common than the neoplastic ones and that the feline chronic gingivostomatitis is the most frequent oral cavity lesion.
