“…In sheep, high prevalence of SCC in Australia and South Africa was attributed to increased exposure of the perineum to solar radiation following tail docking to reduce the incidence of cutaneous myiasis (Hawkins et al, 1981;Tustin et al, 1982). Although SCC occurred on other parts of the goat, the perineum was the most common site as previously reported by Radostits et al, (1994); Baipoledi (2001). In addition to shape, size, posture of the tail and lack of pigmentation of the underside of the tail, it was highly likely that solar radiation plays a role in the predisposition to perineal SCC (Baipoledi 2001).…”

In a 2-year survey of tumors occurring in ruminants reared in El-Dakahlyia Governorate, Egypt during the period from October 2016 to October 2018. 66 tumor masses were collected: 60 from cattle, 2 from buffaloes and 4 from sheep. According to histopathology of cattle tumors, 15 neoplasms were diagnosed as cutaneous papilloma, 5 neoplasms were diagnosed as cutaneous fibropapillomas, 25 neoplasms were diagnosed as squamous-cell carcinoma (SCC) of the eye; 8 neoplasms were diagnosed as SCC of perineum, 1 neoplasm was diagnosed as SCC in skin of muzzle, 2 neoplasms were diagnosed as epulis in dental pad, 2 neoplasms were diagnosed as vaginal leiomyoma, 1 neoplasm was diagnosed as fibroma and 1 neoplasm was diagnosed as liposarcoma. Histopathology of buffalo tumors revealed SCC in head skin (1 case) and buccal cavity (1 case). Histopathology of sheep tumors revealed SCC in skin under the tail (2 cases), skin of groin (1 case) and skin of abdomen (1 case). In conclusion, cattle (60/66) were more susceptible to tumors than buffaloes (2/66) and sheep (4/66). Females accounted for a higher percentage of the neoplasms (47/66) than males (19/66). Adult animals aged above 2 years were more frequently affected than young. The occurrence of epithelial tumors (60/66) was greater than the mesenchymal tumors (6/66). The most common epithelial tumors were ocular SCC and cutaneous papilloma. Number of malignant tumors (41/66) was higher than number of benign tumors (25/66). Variable degrees of bovine SCC differentiation were detected. Meanwhile ovine SCC appeared only well differentiated.

“…Além disso, não há como ignorar a óbvia correlação entre incidência solar e grau de pigmentação da pele dos animais que desenvolvem essas neoplasias. De fato, nesse estudo, a neoplasia somente ocorreu em animais com a pele da região perineal despigmentada, similar ao relado por Baipoledi (2001).…”

A prevalência dessa enfermidade é desconhecida nas populações caprinas das diversas regiões do Brasil.…”

Carcinoma de células escamosas perineal em cabras no Pará

Pesq. Vet. Bras. 29(5): 421-427, maio 2009 RESUMO.-Descreve-se a ocorrência de carcinoma de células escamosas (CCE) bem diferenciado em caprinos de duas propriedades no Estado do Pará. Foram observadas a prevalência, a correlação com a pigmentação da região perineal e as características macro e microscópi-ca das lesões. As lesões consistiram em tumores no períneo, com grau de desenvolvimento, diâmetro e forma variados. Em uma propriedade no município de Viseu, dos 347 caprinos, 20 apresentaram CCE (5,8%). A neoplasia só foi observada em animais com a região perineal despigmentada. Em outra propriedade, no município de Garrafão do Norte, descreve-se a ocorrência de três casos em um rebanho de 400 caprinos (0,75%). A elevada ocorrência deste tumor deve-se, provavelmente, à despigmentação do períneo e à cauda curta e elevada das cabras, que expõe a região perineal à alta incidência de radiação ultravioleta naquela região. TERMOS DE INDEXAÇÃO: Carcinoma epidermóide, caprinos, patologia. INTRODUÇÃONos últimos anos, a caprinocultura vem crescendo no Pará, Estado que possui o maior rebanho da Região Norte, embora alguns fatores desfavoráveis para a espécie como altos índices pluviométricos, alta umidade relativa do ar e manejo sanitário deficiente, predisponham esses animais a enfermidades diversas. Como se trata de região equatorial, lesões de pele devidas à elevada incidência de raios ultravioleta adquirem destaque.De fato, neoplasias da pele e anexos são comuns em animais que vivem em países de clima tropical como o Brasil, em especial pela exposição crônica dos animais à radiação ultravioleta (Goldschmidt & Hendrick 2002 diomedes@ufpa.br Squamous cell carcinoma in goats of two farms in the State of Pará is described. Prevalence, correlation with the pigmentation of the perineal area and macro and microscopic characteristics of the lesions were studied. The tumors on the perineum were of varied development degrees, diameters and forms. On one farm, in the county of Viseu, from a total of 347 goats, 20 presented the neoplasia (5.8%). On the second farm, in the county of Garrafão do Norte, three cases of squamous cell carcinoma in a herd of 400 goats (0.75%) were observed. The tumor was only observed in animals in which the perineal area was despigmented. The high incidence of this tumor appears to be due to lack of pigmentation at the períneo and the high and short tail of the goats, that exposes the area to intense ultraviolet radiation in the tropics.INDEX TERMS: Squamous cell carcinoma, goats, pathology.

“…In goats, SCC is characterized by its invasive nature and risk factors shared by other species. It is most commonly found on the perineum ( 7 , 8 ). Studies have suggested other risk factors in goats including a predisposition for females and smaller breed animals ( 9 ).…”

Mycobacterial Cell Wall Stimulant in the Treatment of Squamous Cell Carcinoma: A Case Series Regarding Treatment in Equine, Bovine and Caprine Patients

et al. 2021

View full text Add to dashboard Cite

Squamous cell carcinoma (SCC) is a common dermatological neoplasia found in large animal species. Treatment options, such as surgery and cryotherapy may be difficult or not feasible. Alternative therapies, such as immunomodulating drugs, can potentially be used for companion large animals. The hypothesis of the following retrospective study is: following multiple intravenous and intralesional injections of a mycobacterial cell wall stimulant (MCW) regression of SCC in equine, bovine and caprine patients will be observed. In this observational-retrospective case series, patients included are 2 bovine, 2 caprine and 3 equine patients. The medical records at two different teaching veterinary hospitals were searched for cases with a positive histopathological diagnosis of squamous cell carcinoma that were subsequently treated with MCW, as either the sole therapy, or in conjunction with other therapies. Seven cases were included in this retrospective study. The median duration of therapy was 56.5 days, with 3 of the 7 patients being euthanized. Significant complications were seen in 3/7 patients. Repeated injections of a MCW may lead to reduction in lesion size of SCC in some cases, but long-term resolution is unlikely and the risk of significant complications is high; due to limited sample size and the variety in species, it is difficult to conclude if MCW is an effective therapy for SCC.
