Abstract :In the survey study, a total of 19 canine mast cell tumors were examined with regard to sex, age, breed of dogs, tumor location, and pathological findings in the period of 1960-1999. The majority of tumors occurred in males insert ignore into journalissuearticles values(78%); and between the ages of 6 and 11 years insert ignore into journalissuearticles values(67%);. The pointer was predisposed to development of tumors insert ignore into journalissuearticles values(35%);. The hindquarters and hind legs were most commonly involved, followed by the extragenital inguinal area and trunk. The tumors clearly had a site preference for the posterior region of the body insert ignore into journalissuearticles values(79%);. The only extracutaneous tumor was found in the nasal cavity. It was interesting that a tumor was observed in the skin of the tail of the Anatolian Karabash dog. The size of tumors ranged from a nodule 0.5 cm in diameter and weighing 15 gr to a large mass with extensive infiltration of large areas of the dermis which was 19x22x6 cm in dimensions and weighing 1.8 kg. Most of them occurred as well-circumscribed cutaneous nodules, but larger ones were observed to be diffuse poorly delineated oedematous, and more than one as swelling of the skin. Microscopically, tumors were classified as mature insert ignore into journalissuearticles values(40%);, intermediate insert ignore into journalissuearticles values(47%); and anaplastic insert ignore into journalissuearticles values(13%);, and also characteristic findings were described and discussed.
