| Popis: | Mammary gland neoplasms in cattle are rarely observed in the field veterinary diagnostics routine. Therefore, the objective of this study is to report a metastatic mammary carcinoma in a fourteen-year-old Holstein cow in the state of Santa Catarina, Brazil. The animal was diagnosed by the field veterinarian with clinical mastitis that was unresponsive to treatment, and was euthanized due to the poor prognosis. At the necropsy, multiple yellow, firm, and sometimes friable nodules, ranging from 0.1 to 20cm were observed in all mammary glands, lymph nodes, kidneys, spleen, liver, pancreas, mediastinal lymph nodes, heart, and lungs. The final diagnosis of mammary carcinoma was established through the association of clinical, necropsy, histopathological, and immunohistochemical findings. Differential diagnoses included diseases such as bovine tuberculosis and chronic fungal or bacterial mastitis. RESUMO: Carcinomas de glândula mamária em bovinos raramente são vistos na rotina de diagnóstico no campo. Portanto, o objetivo do trabalho é relatar a ocorrência de um carcinoma de mama metastático em uma fêmea bovina de 14 anos, holandesa, no estado de Santa Catarina, Brasil. O animal foi diagnosticado pelo veterinário com mastite irresponsiva a tratamento clínico, e foi eutanasiada devido ao prognóstico desfavorável. Na necropsia foram observados múltiplos nódulos amarelados, firmes, e por vezes friáveis, variando entre 0.1 e 20cm, disseminados em todas as glândulas mamárias, linfonodos, rins, baço, fígado, pâncreas, coração e pulmão. O diagnóstico de carcinoma de glândula mamária foi baseado em achados clínicos, macroscópicos, histopatológicos e de imuno-histoquímica. Os diagnósticos diferenciais incluíram doenças como tuberculose bovina, mastites crônicas de origem bacteriana ou fúngica. |
