Abstract

Transmissible venereal tumor (TVT): epidemiological, clinical and pathological analysis of dogs diagnosed at the Animal Pathology Laboratory of the Veterinary Hospital of UFCG. Aiming to an analysis of epidemiological, clinical and pathological data of case of transmissible veneral tumor (TVT) in canines, a restrospective study of the records of biopsies and autopsies of LPA/HV/UFCG, from January 2003 to December 2013. In this period they were diagnosed 17 cases of TVT, six genital seven extra-genital. Of these, nine werw males and eight females. Metastases occurred in five cases. Most were mongrel dogs (41,2%) of reproductive age, created in peridomestic or wamdering regime and microscopically. Usually there pendunculadas and multinidular masses, characterized histologically by cells round or ovoid, arranged in rows with moderate cytoplasm, vacuoles and large core, round and clear nucleolus. Generally observed is cases, followed by the combination of surgery with chemotherapy (11,8%). In five cases occurred recovery and six animals died or were euthanized with complications or metastasis to parenchymal organs and six was not informed. We conclude that the TVT is a commonly diagnosed cancer in the LPA, occurring genital and genital extra forms mainly in stray dogs and peridomestic. Thus, population control measures and saves responsible campaigns are highly important for reduction of stray animals and consequently of communicable diseases such as TVT.
