RESUMO
Background: Although transmissible venereal tumor (TVT, transmissible venereal sarcoma, Stickers sarcoma) that affects dogs and other canids can be seen in many countries, it especially emerges in the countries which homeless dog population is very high. Female dogs are more susceptible than males. Transmissible venereal tumor is usually transmitted to genital organs during coitus and occasionally by social behavior such as sniffing and licking. The tumor is generally observed in the posterior part of the vagina. The tumor usually appears in various sizes, in the appearance of cauliflower, red and fragile. Metastases are rarely reported in cases with TVT. Metastases have been detected in lung, liver, tonsils, skin, lymph nodes, muscles, spleen. The diagnosis of transmissible venereal tumor is achived by considering the history of the animal, gross lesions, cytological examination and histopathology. Chemotherapy is frequently used in the treatment of TVT. In addition, radiotherapy, cryosurgery, surgical incision and immunotherapy are rarely applied for treatment. Chemical agents such as doxorubicin, vincristine sulfate, cyclophosphamide, methotrexate are preferred for chemotherapy.Case: Metastases to all mammary lobes, cervix uteri, neck, skin, gluteal muscles, the oropharyngeal region, and primary vaginal mass were described in spayed bitch, a 10-year old and mixed breed. The clinical examination manifested, fragile and hemorrhagic masses which resemble cauliflower in the vagina, neck, and inguinal region. Furthermore firm and multilobular masses in all mammary lobes, oropharyngeal region, and gluteal muscles of right leg were detected. Firstly, vaginal cytology was performed in order to confirm...(AU)

O Tumor Venéreo Transmissível é uma neoplasia sexualmente transmissível caracterizada por lesões proliferativas que acomete caninos machos e fêmeas mais jovens, com vida sexual ativa. A neoplasia é vista em vestíbulo e/ou vagina, vulva, pênis e outras regiões de face como focinho, olho e boca. Menoscomumente pode acometer pele e outros tecidos. O tumor venéreo transmissível é a segunda neoplasia demaior incidência em cães. Esse trabalho objetiva relatar um caso clínico atendido na Clínica VeterináriaTrato Vet, em Campinas, submetido a um tratamento eficaz com quimioterapia associado a criocirurgia. (AU)
The Transmissible Venereal Tumor is a neoplasm characterized by sexually transmitted proliferativelesions affecting canines males and females younger, sexually active. The tumor is seen in foyers or vagina,vulva, penis and other parts of the face such as nose, eye and mouth. Less commonly infects skinand other tissues. The transmissible venereal tumor is the second highest incidence of cancer in dogs.This paper aims to review the literature on the subject. Commentetio pathogenic the ories, diagnosis, presentation and treatments available. A case will be treated in clinical Veterinary Clinic Trato Vet in Campinas, this being a case of partial response to treatment more usual, how ever, responsive to theuse of cryosurgery. (AU)
