Plain-English summary
A 15-year-old cat was brought in because it had suddenly gone blind in one eye. The veterinarian found a raised, dark mass inside the eye, which was confirmed to be a type of cancer called choroidal malignant melanoma after the eye was surgically removed and examined. This is the first known case of this specific type of eye cancer in a cat without affecting the iris. Unfortunately, the prognosis for this condition can vary, and further treatment options would depend on the individual case.

Abstract
This report describes the clinical presentation, diagnosis, histological lesions, and prognosis of a primary choroidal malignant melanoma in a 15-year-old cat. The animal was presented for unilateral blindness. On ocular examination, a raised pigmented mass protruding from the posterior pole into the vitreous body was observed by diffuse transillumination and indirect ophthalmoscopy. Ocular ultrasound and computer tomography (CT) scan confirmed localization of the tumor to the posterior segment. The diagnosis of primary choroidal melanoma was confirmed by histopathology after enucleation. To our knowledge, this is the first reported case of a feline malignant melanoma with a primary choroidal localization without iris involvement.
