Epidermotropic metastatic melanoma simulating multiple primary melanomas

Epidermotropic metastatic melanoma is usually distinguished from primary melanoma by the limitation of the epidermal involvement of the metastasis to an area overlying the dermal tumor. We report a case demonstrating multiple epidermotropic melanoma metastases with more extensive epidermal involvement simulating primary melanoma that occurred 20 years after excision of the primary tumor.
