Squamous cell carcinoma in a cat with intraocular and orbital metastases.
A well-differentiated squamous cell carcinoma metastasized to the choroid and retrobulbar tissues surrounding the optic nerve sheath in the left eye of a 15-year-old white female domestic cat. The tumor originated either in the external auditory meatus or in the middle ear and extensively infiltrated the neighboring soft tissue and bone.
