Conjunctival melanoma is a rare but potentially deadly ocular malignancy. It is well known for months or years as a red spot on the eye or as focal conjunctivitis that is resistant to topical medications. It can be clinically confused with more common conditions, such as conjunctival nevus or primary acquired melanosis. Conjunctival melanoma arises from the mucous membrane that lines the surface of the eye.Recent evidence indicates that its incidence is rising. Most patients with conjunctival melanoma report symptoms of a painless brown or pink lesion on the surface of the eye for months or years. They typically seek medical care after the appearance of the lesion changes, thickens, or develops enlarged blood vessels.
