In a study of 358 skin tumours of cats, 47.7% were derived from epithelial tissue and 50.4% from mesenchymal tissue. 1.9% were tumours of the pigmented cells. Fibrosarcomas were the most frequently diagnosed type of skin tumours (25.5%), followed by basal cell carcinoma (18.5%), carcinoma of the squamous epithelium (10.9%) and mastocytoma (9.8%). The average age was 9.5 years for females and 9 years for males, but it varied considerably with the different types of tumour. Squamous cell carcinoma, basal cell carcinoma and fibrosarcoma occurred more frequently among older cats, while mastocytoma and multicentric fibrosarcoma were found more frequently among younger animals. No breed predispositions were observed.
