Multifocal choroidal melanoma in oculodermal melanocytosis in an Asian Indian.

A 51-year-old Asian Indian male with right oculodermal melanocytosis presented with a blurred visual acuity of 20/40. Upon fundus examination, he was discovered to have two independent pigmented choroidal melanomas in the temporal juxtapapillary region and inferiorly, in the region of trace clinical sectoral choroidal melanocytosis. The patient underwent enucleation, and on histopathology the two tumors were found to be in the area of choroidal melanocytosis, in continuity with each other. Multifocal choroidal melanoma is an exceedingly rare diagnosis. Ocular melanocytosis is a known predisposing factor for both unifocal and multifocal melanomas. Lifelong monitoring for uveal melanomas must be done in all patients with ocular melanocytosis.
