A 14-year-old spayed female Japanese cat presenting continuous lacrimation from the left eye for 1 month, had a light pink colored mass on the iris of the left eye with corneal edema. The mass rapidly enlarged and the left whole eye was enucleated 4 months later. Though the postoperative condition seemed well enough, a right head tilt and right circling appeared on day 72 after operation, and became severe day by day. The cat died on day 82 after operation with sudden cessation of breathing. Histopathologically the enucleated eye showed malignant melanoma in the ciliary body, iris, cornea, choroid and bulbar conjunctiva. Metastasis was detected in the kidney and brain stem.
