title: Epidermotropism in melanoma.
abstract: Multiple malignant melanocytic lesions developed in a 54-year-old man 4 years after a primary malignant melanoma (Clark level IV) had been excised and 2 months after taking L-Dopa for Parkinsonism. Several of the recurrent lesions that showed junctional melanocytic components were considered primary melanomas and it was suggested that L-Dopa was responsible for malignant transformation of nevi and for rapid progression of the disease. The case was re-examined and on recent evidence it is likely that these lesions were epidermotropic metastases and that L-Dopa played no part in the progress of this unusual tumor.
