Extragenital primary cutaneous venereal granuloma in dogs: A review of three cases

Three intact male dogs of different breeds were presented to Veterinary Clinical Complex, Tirunelveli with a single cutaneous mass at different locations. Fine needle aspiration cytology (FNAC) smears obtained from the masses revealed the typical cytological features of transmissible venereal tumor (TVT) in all the three cases. None of the cases had lesion in the genitalia. Based on the anamnesis, clinical symptoms and cytological examinations the cases were diagnosed as primary cutaneous transmissible venereal tumors. The animals were treated successfully using Vincristine Sulphate intravenously at the rate of 0.6 mg/m². The response to chemotherapy with Vincristine Sulphate was excellent leading to complete regression of the neoplasm and no relapse.
