Summary A 13‐year‐old Missouri Fox Trotter gelding of chestnut colour was referred for a 6‐week history of blepharospasm and epiphora of the left eye. Due to the presence of irregular corneal masses, superficial keratectomy was performed along with adjunctive strontium‐90 beta irradiation and subsequent topical mitomycin C chemotherapy. A diagnosis of poorly melanised malignant melanoma was made based on histopathological examination and immunohistochemistry. There has been no recurrence of the neoplasm over 10 months of follow‐up. To the authors' knowledge, this is the first documented case of a primary corneal melanocytic neoplasm in a horse.
