TUMOR VENÉREO TRANSMISSÍVEL (TVT) CANINO CUTÂNEO: RELATO DE CASO

Abstract

The Canine Transmissible Venereal Tumor (CTVT) is a common contagious neoplasm that affects canines, especially non-domiciled canines, without manifesting predisposition by sex or breed. The transmission usually occurs through sexual contact, but it can also be through extensive contact with surfaces of other contaminated animals, as well as scratches, licking, biting, or the habit of smelling and licking a carrier animal. Metastases are rare, but can occur in animals with persistent neoplasia for more than two months, with regional lymph nodes, scrotum and perineal area as the most frequent sites. The objective of this study was to report a case of a young, adult, free-living dog with a large volume increase in the lateral side of the left pelvic limb and a smaller one in the inner part of the same limb. We chose surgical resection with biopsy collection due to the characteristics, size and location of the mass. Histopathological examination revealed the presence of neoplastic cells with characteristics compatible with canine venereal transmissible tumor. The animal showed the genital presentation of the disease after the surgery, being treated with vincristine sulfate totalizing five applications he complete remission of the penile tumor and without relapses of the tumors in the limb. It is emphasized the importance of including TVT as a differential diagnosis in cutaneous neoformations.
