Choroidal metastasis of cutaneous malignant melanoma treated by ruthenium-106 plaque irradiation.

Symptomatic dissemination of cutaneous malignant melanoma to the choroid occurs rarely and is a grave prognostic factor. Therefore, choroidal tumors are treated only as a palliative measure. We present a case of cutaneous malignant melanoma with symptomatic metastasis in the choroid OD of a 38-year-old woman. We treated it using brachytherapy with a ruthenium-106 plaque. The tumor totally regressed with restoration of good vision. Twelve months of follow-up showed no systemic spread.
