Abstract

Malignant melanomas are the most common primary intraocular tumors in adults. Nevertheless, these lesions are infrequent. The tumor arises from melanocytes within the choroid. Choroidal melanoma have race predominance, and most often affect white people while incidence among blacks is extremely rare. Median age is 55 years. Choroidal melanomas may have variable coloration, ranging from amelanotic to darkly pigmented, and are typically circumscribed, domed-shaped masses that grow to the vitreous cavity. Choroidal melanoma may metastasize before diagnosis. The tumor can spread hematogenously to the liver, lung, bone, skin, and the central nervous system (CNS).
