This report is of a 38-year-old woman with oculodermal melanosis who presented with painless gradual visual loss for 8 months. Ocular examination showed visual acuity of 20/200 in the affected eye. Dilated fundus examination revealed a large superotemporal choroidal mass with overlying retinal detachment. Histopathology showed epithelioid cell–type melanoma occupying the choroid, ciliary body, and iris. Most of the tumour mass was in the posterior choroid. There was some infiltration of the tumour cells into the inner layers of the sclera without extrascleral extension. Systemic examination did not reveal any other organ involvement. During 14 months of follow-up, there was no evidence of metastasis.
