[Epiluminescent microscopy score for differential diagnosis of dysplastic nevi].

Specific epiluminescent microscopical criteria of histopathologically defined dysplastic nevi are yet unknown. The diagnostic evaluation of dysplasia and atypia is especially based on microscopic assessment of combined morphologic and coloured details of melanocytic lesions. Differences, skin microscopically analysed, between a group of 55 dysplastic nevi and a comparative group of 130 junctional and compound nevocellular nevi were statistically significant for 12 characteristics. Thus a score could be established for surface microscopic differential diagnosis of dysplastic nevi.
