Recurrence of choroidal melanoma after photocoagulation therapy

A 40-year-old man had a small choroidal melanoma in his left eye. The tumor was seemingly erradicated by xenon arc photocoagulation; however, eight years later the tumor recurred along the inferior edge of the chorioretinal scar, and the eye was enucleated. Histopathologic examination of the lesion revealed a spindle B-cell melanoma.
