Neoplasms in swine are rare. This paper describes neoplasms found in swine in the diagnostic routine of a veterinary pathology laboratory in the Central Region of Rio Grande do Sul, Brazil during a 49-year period, during which 2,266 cases of the various affections in swine were diagnosed. Of those 37 cases (1.6%) were neoplasms. In decreasing order of prevalence, the following neoplasms were found: lymphoma (11 out of 37 cases), nephroblastoma (11/37), melanoma (8/37), and papilloma (2/37). Adenoma hepatocelular, carcinoma hepatocelular, cholangiocarcinoma, malignant fibrous histiocytoma, granulocytic sarcoma were each found in one case out of the 37 cases. The gross and histological aspects of these tumors are described and their epidemiology is compared with the data available in the literature for neoplasia in swine |
