Abstract

The diagnosis of canine transmissible venereal tumor (TVT) in based on clinical, cytological and/or histopathological examination. Vincristine sulfate is the conventional treatment of choice. Furthermore, homeopathy is also a therapeutic possibility by the use, for example, of Viscum album, which has been employed in the treatment of cancer. A 2-year-old mixed-breed female dog diagnosed with TVT was orally treated with Thuya occidentalis 6x10-12; topical application of T. occidentalis 9x10-18 in the lesion; and V. album subcutaneous applications in different dilution combinations. The tumor was reduced by about 90% during 150 days of treatment, and the patient had no longer bloody vaginal discharge. The complete remission was accomplished with a single vincristine application (0.025mgKg-1). No tumor was observed a week later, and the cytological examination confirmed the absence of tumor cells. No side effects were verified during the treatment period.
