The purpose of this study was to determine the prevalence and anatomopathological findings of primary and metastatic heart tumors and from heart base tumors diagnosed in dogs from southern Minas Gerais, Brazil. The diagnosis was based on histological characteristics and immunophenotyping of the tumors cells. From 1994 to 2009, 2397 necropsies of dogs were performed. Cardiac neoplasms were diagnosed in 31 dogs (1.29%), where seven (22.58%) were primary and 24 (77.42%) were metastatic. Neoplasms of the heart diagnosed as primary were hemangiosarcoma (1/7) and myxoma (1/7), and, primary of heart base, the chemodectoma (3/7) and ectopic thyroid carcinoma (2/7). Frequency was higher in male dogs (5/7), of Boxer breed (3/7) with mean age of 9.7±1.88 years. In metastatic neoplasms, the frequency was higher in female dogs (15/24), of Rottweiler breed (7/24) with the mean age of 7.5±3.23 years. The T cell lymphoma (7/27) was the most frequent neoplasm, diagnosed as metastatic. |
