Abstract :In this retrospective study, some epidemiologic aspects and histopathologic characteristics of 236 canine mammary tumours diagnosed at the Pathology Department, Faculty of Veterinary Medicine, University of Ankara, from 1973 to 1998 were evaluated. Forty-eight of 236 dogs with tumours insert ignore into journalissuearticles values(23.08%); were poodle, 40 insert ignore into journalissuearticles values(19.23%); were caniche, 30 insert ignore into journalissuearticles values(14.43%); were terrier, 27 insert ignore into journalissuearticles values(12.98%); were German shepherd, 15 insert ignore into journalissuearticles values(7.21%); were pinscher, 48 insert ignore into journalissuearticles values(23.08%); were 13 different breeds and the breeds of 28 insert ignore into journalissuearticles values(11.86%); were not known. Most of the animals insert ignore into journalissuearticles values(96%); were between 5 and 15 years of age. The malignancies obtained in poodle and caniche breeds were more frequent than in other breeds, whereas there was no difference in the distribution of tumour types among breeds. One hundred sixty eight cases of 236 were malignant insert ignore into journalissuearticles values(2 myxosarcoma, 2 fibrosarcoma, 2 fibroosteochondrosarcoma, 1 fibromyxosarcoma, 1 fibromyxomyosarcoma, 2 osteochondrosarcoma, 1 myxomyofibrosarcoma, 68 malignant mixed tumors, 89 carcinoma); and the remaining 68 cases were benign insert ignore into journalissuearticles values(7 multilobular hyperplasia and cystic proliferative changes, 6 adenoma, 7 pericanalicular fibroadenoma, 2 fibroma, 1 osteoma, 2 osteochondroma, 1 myxochondroma, 1 fibromyxochondroma, 1 fibroosteochondroma, 1 fibromyxochondroosteoma, 39 benign mixed tumours);. The locations of tumours were reported in 86 cases as follows: 10 insert ignore into journalissuearticles values(11.6%); in thoracic glands, 27 insert ignore into journalissuearticles values(31.4%); in abdominal glands, 35 insert ignore into journalissuearticles values(40.7%); in inguinal glands and 14 insert ignore into journalissuearticles values(16.3%); in various mammary glands. In addition, it was observed that malignant tumours caused metastasis to visceral tissues insert ignore into journalissuearticles values(lung, liver, kidney, urinary bladder and ovarium); with regional lymph nodes.
