title: Extragenital transmissible venereal tumour associated with circulating neoplastic cells in an immunologically compromised dog.
abstract: An adult male intact boxer was presented because of diffuse cutaneous nodules. Fine-needle aspirate revealed transmissible venereal tumour (TVT) cells. Neoplastic cells were also observed in the peripheral blood. Associated simultaneous diseases included leishmaniosis, demodicosis, papillomatosis and coccidiosis. Immunosuppression may have aggravated disease and triggered widespread metastases. The dog was hospitalized and administered oral amoxicillin/clavulanate, subcutaneous meglumine antimonite to treat leishmaniosis and oral chlortetracycline to treat coccidiosis. Intravenous injection of vincristine at weekly interval was used to treat TVT. A rapid regression of cutaneous nodules was noted; however, intractable diarrhoea developed, eventually leading to death after 18 days. This is the first report describing an unusual case of extragenital TVT associated with circulating neoplastic cells in an immunosuppressed dog presenting with multiple cutaneous nodules.
