Abstract
Transmissible venereal tumour is a contagious tumour frequently found in dogs in Sri Lanka. Generally, canine TVT (cTVT) is transmitted via sexual intercourse and therefore the lesions are typically found in external genitals of dogs. Due to the characteristic cauliflower like gross appearance of gross lesions of TVT, diagnosis of genital TVT is mostly easy and straight forward when confirmed by cytology. However, TVT cells may transplant on mucous membranes other than external genitals due to social behaviours of dogs and produce atypical lesions at extra genital sites. Extra genital TVT is difficult to diagnose, especially when the affected dogs lacking concurrent genital lesions. Only a limited number of extragenital cTVT case reports are published in Sri Lanka and this report provide a comprehensive description of extragenital cTVT in nine dogs presented with a variety of lesions, diagnosis and response to treatment with vincristine sulphate.
