Absract:The presented case includes the vaginal fibrosarcoma hanging out through the lips of vulva of a 3-year old, brown Swiss cow and removal of the mass with operative intervention. In the clinical examination of the cow, no disorder other than the mass was detected. A hemorrhagic, necrotic, lobular mass spreading to various regions of vagina and hanging out through the lips of vulva was identified in clinical examination. The mass with the diameter of 15 x 12.5 x 13 cm was removed from the site by operative intervention. Histopathological and immunohistochemical examinations revealed that the mass was vaginal fibrosarcoma. The cow has been followed up for 6 months postoperatively. No complication or recurrence was observed. In conclusion, we believe that the vaginal fibrosarcoma in the presented case which was diagnosed as a result of histopathological and immunohistochemical examinations in a -3 year old cow will contribute to the scientific literature.

“…As demais (30%) eram vacas sem raça deϐinida, não sendo possível deϐinir o propósito do animal. Em estudos retrospectivos de casos de CCEVs, a idade das vacas variou de 3 a 10 anos (Damodaran et al 1975, Yeruham et al 1999. Entretanto, há descrição em novilha de 15 meses (Yeruham et al 1999) e em vacas de até 13 anos (Wettimuny 1974).…”

“…O CCEV é responsável por perdas econômicas devido à redução na vida reprodutiva (Meyers & Read 1990) ou às condenações em abatedouros (Yeruham et al 1999). Apesar de alguns estudos recentes relatarem, dentre outros neoplasmas em bovinos, a prevalência de CCEVs em algumas regiões do país (Ramos et al 2007, Keller et al 2008, Lucena et al 2011), há escassez de detalhamento dos aspectos epidemiológicos e clínico-patológicos desses neoplasmas em vacas no Brasil, justiϐicando assim a realização deste estudo.…”

Aspectos epidemiológicos, clinicopatológicos e imuno-histoquímicos de carcinomas de células escamosas vulvares em 33 vacas

RESUMO.-Carcinomas de células escamosas vulvares (CCEVs) em bovinos foram estudados retrospectivamente quanto à prevalência, epidemiologia, quadro clinicopatológico e aspectos imuno-histoquímicos. O Vulvar squamous cell carcinomas (VSCCs) in cattle were retrospectively studied regarding the prevalence, epidemiology, clinicopathological, and immunohistochemical aspects. The degree of vulvar pigmentation was also evaluated. In the 48 years analyzed, necropsy and biopsy reports of 7,483 cattle were found. Out of these, 664 (8.87%) cases of various neoplasms were identiϐied; 33 (4.97%) of these cases were of VSCCs. Nineteen cows were Holstein, three were Charolais, one was Jersey, and 10 were mix breed cows. Grossly, the main change was vulvar swelling, with bleeding and concomitant myiasis. The tumor masses were ϐirm, ulcerated and with yellow areas. It was possible to reevaluate microscopically 30 out of the 33 cases. Eight of them were well differentiated, 17 were moderately differentiated, and ϐive were poorly differentiated VSCCs. The evaluation of squamous intraepithelial lesions (SILs) was performed in 21 cases. Epithelial hyperplasia was observed in 10 cases, mild dysplasia in two, moderate in one, and severe in ϐive cases; in three cases no SILs were observed. Fontana-Masson stain for melanin was performed in 21 cases. In 17 cases the epidermal pigmentation was absent; it was mild in two and moderate in other two cases. Independently of the degree of differentiation, most neoplastic keratinocytes were strongly positive for bovine pancytokeratine through the immunohistochemistry (IHC) technique. Bovine papillomavirus was not detected by IHC in this study.INDEX TERMS: Vulvar neoplasms, squamous cell carcinoma, cattle diseases, immunohistochemistry.

Fatores de risco associados à ocorrência de carcinoma de células escamosas em ruminantes e equinos no semiárido da Paraíba

et al. 2012

Neste trabalho descreve-se a frequência de carcinomas de células escamosas diagnosticados pelo Laboratório de Patologia Animal (LPA) do Hospital Veterinário da Universidade Federal de Campina Grande (UFCG) em bovinos, ovinos, caprinos e equinos no semiárido da Paraíba, durante o período de 1983 a 2010, analisando dados epidemiológicos e fatores de risco. Foi realizada a análise dos fatores de risco, mediante o teste de qui-quadrado de aderência, considerando como variáveis espécie, raça, sexo, idade e localização da massa tumoral. Durante o período foram registrados 3.153 diagnósticos provenientes de biópsias e necropsias. Destes, 81 casos (2,7%) foram de carcinomas de células escamosas. A frequência por espécie foi de 4% (42/1052) em bovinos, 2,5% (15/603) em equinos, 1,7% (12/709) em ovinos e 1,5% (12/789) em caprinos, sendo significativamente maior em bovinos (p<0,001). Todos os casos apresentavam características histológicas de CCE, variando apenas o grau de diferenciação celular. Em bovinos e caprinos, a frequência do tumor foi significativamente maior em animais adultos (p<0,001 e p<0,005, respectivamente). Nos bovinos a localização preferencial foi em olhos e região periocular (p<0,001) e nos ovinos na pele (p=0,018), principalmente na cabeça, enquanto que nas outras espécies não foram encontradas diferenças significantes na localização do tumor. Sugere-se que a maior frequência de CCE em bovinos deve-se à constituição do rebanho, formado predominantemente por fêmeas da raça Holandesa.
