- Abstract: Over the 42 month period from January 2003 to June2006, a total of 2,952 canine biopsy specimens werereceived from the Veterinary Medical Teaching Hospitalof Seoul National University and from veterinary practitionersacross the nation. Out of these, 748 (25.34%) cases werediagnosed as canine cutaneous tumors in the Departmentof Veterinary Pathology, College of Veterinary Medicine,Seoul National University, Korea. Thirty-eight differenttypes of cutaneous tumors were identified and categorizedinto epithelial and melanocytic tumors (56.95%), mesenchymaltumors (38.90%), and hematopoietic tumors (4.14%)located in the skin. Among these, 69.25% were benign and30.74% were malignant. The top ten most frequentlydiagnosed cutaneous tumors were epidermal and follicularcysts (12.70%), lipoma (11.36%), mast cell tumors (8.82%),cutaneous histiocytoma (7.49%), basal cell tumors (6.82%),sebaceous gland adenoma (6.68%), sebaceous glandhyperplasia (5.08%), hepatoid gland adenoma (3.61%),apocrine adenocarcinoma (3.07%), and fibroma (2.81%),in order of prevalence. They comprised 68.45% of allcutaneous tumors. These top ten cutaneous tumors weredistributed on the trunk (30.08%), head and neck(20.9%), extremities (19.14%), anal and perianal area(8.59%), and tail (3.91%). The age of the dogs with the tenmost frequent tumors had a mean age of 8.3 years, with arange of 2 months to 19 years. When all types of tumorswere considered together in the entire population, therewas no difference in incidence according to sex.
