Plain-English summary
A 10-year-old male cat was diagnosed with an eyelid tumor, which is a type of growth that can occur on the eyelids. The study found various types of tumors, with squamous cell carcinoma (SCC) being the most common, especially in older cats. While some tumors like mast cell tumors (MCTs) and hemangiosarcomas (HSAs) did not come back after surgery, SCCs often recurred and had a shorter average survival time of about 7.4 months. This highlights the importance of early detection and treatment for eyelid tumors in cats.

Abstract
Submissions to the University of Tennessee pathology service from June 1999 to June 2008 were searched for feline cases of tumors involving the eyelids or nictitans. Forty-three tumors were identified. The average age at diagnosis was 10.4 years. Significantly more males than females had eyelid tumors. There were 12 squamous cell carcinomas (SCCs), 11 mast cell tumors (MCTs), 6 hemangiosarcomas (HSAs), 4 adenocarcinomas (ACAs), 3 peripheral nerve sheath tumors (PNSTs), 3 lymphomas, 3 apocrine hidrocystomas (AHCs), and 2 hemangiomas. Cats with MCTs were significantly younger than cats with all other tumor types combined. In contrast, cats with SCCs were significantly older than cats with other tumor types. The HSAs and SCCs were significantly more likely than other tumors to occur in nonpigmented areas. The MCTs, HSAs, AHCs, and hemangiomas did not recur after surgical excision. In contrast, the lymphomas, ACAs, SCCs, and PNSTs frequently recurred and/or resulted in death or euthanasia of the cat. The SCCs were significantly more likely to recur than the MCTs. The average survival time for cats with SCCs was 7.4 months. Although eyelid MCTs have been reported in cats, the prevalence in this study is much higher than previously described.
