“…Dados de pesquisas realizadas em abatedouros de suínos em vários países (Misdorp 2003, Ogihara et al 2012 indicam que o linfoma é o neoplasma mais frequente nessa espécie. Na França, a taxa desse neoplasma tem sido estimada em 6,5 casos por 100.000 abates, chegando a aproximadamente 41% de todas as condenações relacionadas a neoplasmas (Jacobs et al 2002).…”

“…Linfomas são relatados principalmente em suínos com menos de um ano de idade (Jacobs et al 2002, Ogihara et al 2012) e os achados observados neste estudo confirmam esse fato: oito suínos (72,7%) foram considerados jovens (em torno de seis meses de idade -animais de terminação) e apenas dois suínos foram considerados adultos (animais de reprodução). Neoplasmas originários do sistema hematopoiético, como o linfoma, são os mais prevalentes entre animais jovens, especialmente em cães (Fighera et al 2002).…”

“…Neoplasmas originários do sistema hematopoiético, como o linfoma, são os mais prevalentes entre animais jovens, especialmente em cães (Fighera et al 2002). Em suínos, acredita-se que estejam relacionados a uma herança autossômica recessiva (Jacobs et al 2002). Em um dos suínos não havia menção de idade no protocolo.…”

“…A literatura não relata predisposição racial (Jacobs et al 2002). Com relação ao sexo, cinco eram fêmeas (45,5%); e dois eram machos (18,2%), o que está de acordo com outros estudos, que relatam fêmeas duas vezes mais afetadas do que machos (Jacobs et al 2002, Ogihara et al 2012. Em quatro protocolos (36,3%) não havia menção do sexo.…”

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.

“…This finding is typical of metastatic lymphosarcomas involving the central nervous system in other species (Koestner and Higgins, 2002) but has not been reported in a cervid species with solitary or multicentric lymphoma. In comparison, multicentric enzootic lymphosarcoma in domestic cattle often results in infiltration of the central nervous system (Jacobs et al, 2002). In contrast to multicentric forms, primary lymphosarcomas in the central nervous system are characterized by deep-seated solitary masses, and these tumors are generally of Tcell origin (Koestner and Higgins, 2002).…”

Multicentric T-cell Lymphosarcoma in a White-tailed Deer (Odocoileus virginianus)

ABSTRACT:An adult female white-tailed deer (Odocoileus virginianus) with a history of shaking, ataxia, and severe debilitation was submitted for examination. Macroscopic lesions included severe emaciation, severe abdominal and mesenteric lymphadenopathy, and several rumen-associated masses. Microscopically, the ruminal masses and lymph nodes were infiltrated by pleomorphic neoplastic lymphocytes. Similar lymphoblasts were associated with the leptomeninges, choroid plexus, and the intestinal mucosa; these cells were intensely positive for CD3 antigen, indicating their T-cell origin. Lymphoproliferative viruses (bovine leukemia virus and malignant catarrhal fever virus) or epizootic hemorrhagic disease virus were not detected by polymerase chain reaction. To our knowledge, this case represents the first report of the immunophenotype of a multicentric lymphosarcoma, metastasis involving the brain, and epitheliotropic lymphoblasts in a whitetailed deer.
