Plain-English summary
An 11-year-old female spayed Boxer was brought to the emergency vet for eye discomfort. The vet found that the dog had developed a uveal schwannoma, a type of tumor usually seen in blue-eyed dogs, despite her having brown eyes. The affected eye was removed due to glaucoma, and tests confirmed the diagnosis. Fortunately, follow-up evaluations showed no signs of the tumor spreading, and the dog is currently healthy.

Abstract
An eleven-year-old, female spayed Boxer dog was diagnosed with a uveal schwannoma (formerly known as the spindle cell tumor of the blue-eyed dog or SCTBED) despite having a uniformly brown iris. The patient presented to emergency for ocular discomfort, and the right globe was subsequently enucleated due to glaucoma and submitted for histopathology. Upon histopathologic evaluation, a uveal schwannoma was diagnosed and confirmed with immunohistochemical staining. Complete metastatic evaluation 1 and 6 months after initial presentation did not reveal evidence of metastasis, and the dog remains systemically healthy. This case represents a unique variant of uveal schwannoma and is relevant because although the vast majority of these tumors occur in blue-eyed dogs, clinicians should not completely rule out this tumor as a differential based on the iris color.
