The aim of this study was to make a retrospective evaluation of lymphoma cases that came to the Pathology Department of Ankara University, Faculty of Veterinary Medicine between the years 1985 and 2015. Forty-eight lymphoma cases formed our study material. Out of 1362 tumor cases diagnosed in dogs these 31 years, 38 cases (2,79%) were reported as lymphomas. While in cats, lymphomas accounted for 10 (2,54%) of 394 tumor cases. The mean age of lymphoma in dogs was 7 years old. Among lymphoma cases in dogs 24 cases (63%) were male and 14 cases (37%) were female. Rottweiler and Mix Breed were the breeds with higher incidence. According to the localization, our cases were classified into multicentric (38%), cutaneous (32%), alimentary (16%), mediastinal (8%) and extranodal (5%). Lymphoma cases reported in cats were located as following; 3 in the intestines, 2 in the skin and 5 in the lymph nodes. The mean age was 9 years old; and among 10 cases of lymphoma, 4 of the cases were female and 5 were male. 3 cases were of Mix Breed, 3 were Tabby Cats and 2 Orange Tabby Cats. Of the 10 cats used in the study, 2 had no recorded breed and 1 had no recorded gender. While more than the half of lymphoma cases were previously reported in cats under 5 years age, in our case only 2 cats were under 5 years age (1 and 2,5 years old) and the left 8 cats were about 6 years age or more.
