Although rare, less than ten per million per year, it's the most common primary intraocular tumor in adults, it arises from choroidal melanocytes. It may appear as an elevated mass in the fundus which may be orange or brownish in color and also be unpigmented. In many cases the presentation is by exudative retinal detachment.
The most important differential diagnosis is choroidal metastasis from a malignancy in a distant organ. Secondary malignant deposits are more common than malignant melanoma.
Treatment of choroidal melanoma depends on its size and associated complications . It may include surgical excision of the tumor, radiotherapy or removal of the eye ( enucleation)
