VETERINARY MEDICINE

Definition A histiocytic tumour of dogs and other canids which mainly affects the external genitalia, and is transmitted horizontally during copulation, as well as by sniffing, licking and biting.

CTVT cells have fewer chromosomes than normal canine host cells and are genetically unrelated to the host cells. The tumour has a cauliflower-like in appearance, affecting the penis or prepuce in males and the vagina or labia in females, rarely also the mouth or nose. Surgery is difficult due to the location; chemotherapy with vincristine, vinblastine, and doxorubicin effect long-term remissions, so Rover can happily hump your leg til he dies of old age. 

Synonyms Canine transmissible sarcoma, canine transmissible venereal sarcoma, infectious sarcoma, Sticker tumour, transmissible venereal tumour, venereal tumour 

The accompanying image lends new meaning to the imperitive, Duck!
