Plain-English summary
A 14-year-old spayed female domestic short-haired cat was brought in for a mass in her right eye, which was also blind. The vet found two different growths: one pink and another red-to-brown, which was mostly on the cornea. The cat underwent surgery to remove the affected eye tissues, and tests revealed she had both squamous cell carcinoma (a type of skin cancer) and a hemangioma (a benign tumor of blood vessels). This case is notable as it’s the first reported instance of both tumors occurring together on a cat's eye surface.

Abstract
A 14-year-old spayed female domestic short-haired cat was presented for evaluation of a mass in the right eye. Ophthalmic examination revealed a blind right eye and presence of two distinct masses: a pink and a red-to-brown mass, the latter occupying most of the cornea and part of the conjunctiva. Exenteration was performed under general anesthesia, and the ocular tissues were processed routinely for histopathology. Upon microscopic examination, a malignant epithelial neoplasm and a benign vascular neoplasm were present in the cornea. The conjunctiva and the third eyelid were also affected. Upon immunohistochemistry, the epithelial tumor was positive for cytokeratin and negative for vimentin and the endothelial tumor was negative for cytokeratin and positive for vimentin. A diagnosis of squamous cell carcinoma (SCC) and hemangioma was made. The SCC was affecting the cornea, bulbar conjunctiva (lateral and inferior) and the base of the third eyelid, whereas the hemangioma was affecting the cornea and medial limbus. To the authors' knowledge, this is the first report of concomitant SCC and hemangioma affecting the ocular surface in a cat.
