Transmissible veneral tumor of dogs, also known as the transmissible veneral sarcoma, infective sarcoma or stiker sarcoma, is one of the few tumors that are transmitted by contact off sick and healthy individuals, mainly during coitus, or sniffing, biting and licking. TVT is almost always located on the external genitalia, and in the males the tumor is usually on the caudal part of the penis, bulbus penis and on the internal preputial mucosa. In the females, the neoplasm is usually found in the posterior part of the vagina, vestibule of vagina, urethral orifice and in the vulva. TVT may also develop at extragenital sites, even when there are no genital lesions, such as the skin, nasal cavity or the mouth, conjunctiva and eyes. It was first described by Russian veterinarian Novinski in 1876, who proved that the tumor can be transmitted from sick to healthy dog by tumor cell transplantation. Clinical symptoms are often discharge from the male foreskin, or vagina in females, urinary retention due to urethral obstruction and in the nasal or oral forms of TVT: orinazal fistules, rinorrhagy, enlargement of submandibular lymph nodes. There are several approaches regarding the treatment of TVT, the surgical removal of tumor, chemotherapy or a combination of these two types of treatment. Surgical removal alone is often not enough because recidives might occur, while combination with cytostatic gives good results. Radiotherapy can be used in cases where chemotherapy has not yielded good results.
