Abstract: ABSTRACT. - In a survey for lesions in cattle in abattoirs from January 2011 to July 2014, 544 lesions were found, of which 65 were neoplasms. Forty two percent of those were of mesenchymal origin; 37% were epithelial; 14,5% were neural crest derivatives; 5% were sex chord derived tumors and 1.5 was from the peripheral nervous system. The most common tumor found was lymphoma (28% of all tumors), most of them as part of the enzootic leukosis complex. Squamous cell carcinoma was the second most frequent tumor (1… Show more

“…From the authors' knowledge, the current paper is the first report of bovine death by HCC in Bahia to date. In this region liver tumors are not frequent, and most of the descriptions are related to the incidental findings of slaughterhouses [24]. However, the possibility of aflatoxin involvement in the carcinoma etiology of the present case can not be ruled out, since corn was part of the diet provided to the animal, and in Bahia have reports of contamination by this fungus in cereals used in animal feed [1,20].…”

“…Although primary liver diseases are rare in farm animals, except for cases resultanting of intoxication [18], hepatocellular carcinoma (HCC) is the most frequent hepatic neoplasm in ruminants [15]. In cattle the reports are scarce [6,10,12], most of them coming from slaughterhouses, thus not allowing much data from HCC in this species [4,5,7,24].…”

“…Leiomiossarcoma é uma neoplasia maligna de músculo liso, não muito frequente em bovinos, porém, já foi relatada no útero (TESSELE et al, 2016), e na vagina (SAUT et al, 2013). No presente estudo, a neoplasia foi diagnosticada em um bovino que estava clinicamente apático e anoréxico, sendo que na avaliação post mortem dos pré-estômagos e estômago, observou-se nódulo infiltrativo de 15X10 cm, consistência firme, de coloração esbranquiçada ao corte, aderindo a serosa do rúmen ao abomaso.…”

“…Dentre as lesões detectadas no exame post mortem e, eventualmente, no ante mortem, estão os neoplasias (TESSELE, 2016). Estes podem ter sua origem em alterações genéticas herdadas e que estarão presentes em todas as células dentro do organismo, ou de alterações somáticas que se acumulam nas células e tecidos individuais do corpo ao longo do tempo, podendo ter sua origem em causas química, física (radiação) ou infecciosa (KUSEWITT, 2013).…”

“…Em bovinos, é uma das principais neoplasias diagnosticadas juntamente com linfossarcoma [7,14,15,17]. Mais comumente afeta animais taurinos, sendo rara em bovinos Nelore [7,14,15], o que provavelmente é relacionado a maior pigmentação cutânea destes [21].…”
