Cutaneous squamous cell carcinoma is a common tumor in cats and frequently occurs on the nasal planum and the pinnae. The medical records of 61 cats were reviewed for this retrospective study. Typical presentation was an older (median age, 12 years) cat with an erythematous, crusty, and erosive lesion. Methods of treatment included surgery, radiation, and cryotherapy. Disease-free interval and survival time were calculated for each case and grouped according to lesion location and treatment type. All treatments were found to be effective, with surgery resulting in the longest disease-free interval (median, 594 days).
