Abstract:
The present study was undertaken to study the incidence of skin tumours in canine population. A total of 160 dogs were diagnosed with skin tumours in the study period. Mast cell tumours 22 (13.75%), sweat gland adenocarcinoma 22 (13.75%), lipoma 18 (11.25%), histiocytoma 14 (8.75%), trichoblastoma 10 (6.25%) and perianal gland adenoma 10 (6.25%) were the tumours with highest order of occurrence. The tumours were recorded in 16 different breeds with the highest number of cases recorded in non-descript 55 (34.38%) followed by Labrador 46 (28.75%) and Spitz 19 (11.88%). Of the cases recorded, 109 (68.13%) were males and 51 (31.88%) were females. The highest incidence of skin tumours was observed in dogs belonging to the age group of 6-10 years 82 (50.63%) followed by 50 (31.25%) in dogs of 1-5 years age group. In the age group of more than 10 years, 25 (15.63%) cases were recorded. Only 3 (1.88%) cases were observed in young dogs of less than one year old. Location wise, higher incidence was observed in limbs 53 (33.13%), followed by trunk 39 (24.38%), head 32 (20.00%), neck 15 (9.38%), perianal region 15 (9.38%) and tail 6 (3.75%) respectively. Of the skin tumours identified, 73 (45.63%) were benign and87 (54.37%) were malignant.
