Atypical Presentation of Uveal and Conjunctival Melanoma in the Anterior Segment

Ocular melanoma is a rare malignancy arising from melanocytes of the uvea, the conjunctiva, and the orbit. Uveal melanoma is the most common intraocular malignancy in adults, accounting for 85-95% of ocular melanomas [1-3]. The conjunctival form accounts for 5% of ocular melanomas. Uveal and conjunctival melanoma are very distinct from each other biologically. We describe a case of conjunctival melanoma and a uveal melanoma both presenting as large masses of the anterior segment.
