Cutaneous metastasis of ocular malignant melanoma. An unusual presentation simulating blue nevi.

Cutaneous metastases from primary ocular melanoma are not well characterized in the literature, and the occurrence of cutaneous metastases in the absence of other systemic involvement is distinctly uncommon. A case of primary ocular malignant melanoma is reported in which the only evidence of metastatic disease initially was skin lesions that simulated cutaneous blue nevi. Knowledge of this patient's history of ocular malignant melanoma coupled with a review of the clinical and histopathologic specimens was necessary to arrive at the diagnosis. This case illustrates and characterizes an unusual presentation of cutaneous metastases of primary ocular melanoma.
