Neoplasms have afflicted humans and animals since Prehistorical times and are now among the illness of major impact on the health of both species. For centuries, scholars have been trying to unravel the oncogenesis process seeking to determine the triggering factors associated to the disease in order to better fight it and prevent it. In the canine species, among the neoplasms of major occurrence are those of epithelial origin which represent 50% of all the diagnosed tumors of the specie. Of these tumors, the majority present aggressive behavior, compromising the life quality of the afflicted animals and, frequently , leading to death. Before that, this retrospective study aimed analyze the data files of Setor de Patologia Animal da Escola de Veterinária e Zootecnia da Universidade Federal de Goiás (SPA-EVZ- UFG), in the period of January, 2006 to December, 2018, selecting all the epithelial neoplasm diagnoses in dogs. Thus, were cataloged 973 cases, comprehending 66 distinct diagnoses from which malignant tumors prevailed (73,8%) . Tumors of the mammary gland obtained higher frequency (72,7%), followed by the cutaneous tumors (20,5%) and tumors in other regions (6,8%). Bitches represented 85,9% of all animals, while only 14,1% corresponded to males. There was prevalence of elderly animals (68,6%) and dogs without defined breed (30,2%). However, among the dogs with defined breed, the Poodle (15,4%) and the Dachshund (10,1%) highlighted. Among the mammary tumors the carcinoma in mixed tumor (14,9%), complex carcinoma (12,6%), carcinosarcoma (11,9%), benign mixed tumor (9,8%) and the solid carcinoma (8,9%) had major representativity. The squamous cell carcinoma (34,7%) and sebaceous adenoma (11,6%) featured between the cutaneous tumors, in its turn the ameloblastoma (38,8%) presented higher frequency among the other epithelial neoplasms observed. In conclusion, skin and mammary gland neoplasms obtained higher representativity between the epithelial tumors observed, with higher incidence of those with malignant behavior, being dogs without defined breed more afflicted.
