Estágio supervisionado obrigatório tumor venéreo transmissível: relato de caso

Abstract

(ESO III) at the Jerônimo Dix-Huit Rosado Maia Veterinary Hospital - UFERSA, in association with the Laboratory of Veterinary Microbiology - LAMIV, at the Mossoró - Rio Grande do Norte campus. was carried out during the period from November 6, 2018 to January 11, 2019, accounting for the workload of 240 hours of traineeship related to compulsory III, in the small animal medical clinic sector, where clinical and hospital routine. In addition to the laboratory of veterinary microbiology (LAMIV), where it was possible to observe the diagnostic routine. Of all the cases followed, 14 dogs, all without a defined race (SRD), with ages between 2 and 8 years old, were affected by transmissible venereal tumor (TVT). Of the patients treated, clinical signs were observed in common, such as the presence of a voluminous, hyperemic and friable mass in the genital region and in a punctual way, as constant bleeding, apparently without predilection for race or age, being considered an individual variation of the organism in response to the infectious process. In general, the general clinical condition of the patients was directly related to the tumor characteristics, where the more advanced the condition, the larger the tumor and, therefore, the more debilitated the patient was. The presumptive diagnosis was established through the combined analysis in the anamnesis and physical examination of the patients, and later the suspicions were confirmed, through the clinical cure of the patients after the treatment, without relapses. After the clinical examination, vincristine sulphate treatment at the dose of 0.025mg / kg, every 7 days until total regression of the tumor, totaling, on average, 10 applications of the chemotherapeutic was started. Soon after the third administration of the drug, a considerable improvement in the picture can be observed, by reducing the edema of the genitalia, with the involution of the tumor, as well as the hemorrhagic interruption, in the cases in which it was observed. Treatment was terminated with a final administration of the chemotherapeutic agent even after complete tumor remission, and sequential surgical sterilization was recommended. The treatment based on vincristine sulfate demonstrated efficacy and safety, and no side effects related to medication were observed in the present study. Therefore, the stage was of paramount importance for the professional improvement and still the transmissible venereal tumor is a possible pathology of early clinical diagnosis, because the sooner the appropriate treatment is instituted, the easier the recovery and control of the spread of the disease.
