Resumo
A crescente popularidade dos furões como animais de companhia tem vindo a trazer novas luzes às mais diversas áreas da medicina veterinária em relação a esta espécie. Uma delas é a oncologia, onde um maior número de dados disponiveis referentes a neoplasias tem vindo a mudar o que se pensava saber sobre estas patologias em furões. Sendo as neoplasias cutâneas e tegumentares uma parte significativa do total de neoplasias observadas, esta dissertação teve o objectivo de recolher os dados epidemiológicos e características histológicas em neoplasias tegumentares em furões domésticos. Foi feita uma pesquisa por palavras-chave e diagnósticos codificados na base de dados da SDPV-UAB a fim de recolher esta informação e 40 amostras de neoplasias correspondiam aos critérios de inclusão neste estudo. As neoplasias tegumentares tiveram uma prevalência de 31,6% de todas as neoplasias encontradas em furões, sendo superiores ao descrito, assim como as neoplasias consideradas malignas, podendo-se relacionar com factores de maneio reprodutivo, alimentar e médico, assim como localização geográfica. Os tipos de neoplasia tegumentares mais comumente encontradas foram os mastocitomas cutâneos (17: 42,5%), os tumores de glândulas sebáceas (6: 15%) e tumores de glândulas apócrinas (6: 15%). A idade dos furões afetados variava de inferior a 6 meses a mais de 10 anos de idade. A incidência neoplásica era mais elevada entre a faixa etária dos 4 aos 7 anos, sendo que a média de idade para ocorrência eram os 5,6 anos. Não se observou predileção de género embora se observassem maiores prevalências em fêmeas e machos esterilizados e castrados, respetivamente. As restantes prevalências de neoplasias observadas coincidiam com as descritas a nível bibliográfico.
The rising popularity of ferrets as pets has been bringing new lights to different veterinary fields related to this species. One of these fields is oncology, where the increasing data available regarding neoplasias has been changing what we thought we knew about these diseases in ferrets. Being the cutaneous and tegument neoplasias a very large part of all the neoplasias in ferrets, this dissertation had the objective to collect epidemiological data and histologic characteristics on integumentary neoplasms in pet ferrets. A keyword and code search was made at the SDPV-UAB database to collect the information and 40 neoplasms met the criteria for inclusion in the study. Integumentary neoplasms were found to have a prevalence of 31,6% of all neoplasms found in the ferret. This is a higher number than the observed by other authors, as well as the malignant neoplasia found, and could be related to husbandry practices and geographic location. The most common tumor types were mast cell tumor (17: 42,5%), sebaceous glands tumor (6; 15%) and apocrine glands tumor (6; 15%). The age of the affected ferrets ranged from less than 6 months to more than 10 years of age. Tumor incidence was highest in ferrets between 4 and 7 years of age; the mean of age for neoplasm occurrence was of 5,6 years. No sex predilection was found, although higher prevalence of integumentary neoplasms was observed in neutered females and males. The other observed prevalences were similar to those described in the bibliography.
