Solitary metastasis of choroidal melanoma to the contralateral eyelid.

A 60-year-old man developed a subcutaneous mass in the right lower eyelid 2 1/2 years after enucleation of the left eye for a mixed-cell-type choroidal melanoma. Excision of the subcutaneous eyelid mass revealed the tumor to be a malignant melanoma composed of spindle B cells similar to those in the intraocular tumor. The patient's systemic evaluation, including liver enzymes, has remained normal, with no signs of further metastasis and no evidence of another primary melanoma for 14 months of postexcision follow-up. The significance of the rare occurrence of isolated metastatic melanoma from the choroid of one eye to the eyelid of the other is discussed.
