The histopathology of dysplastic nevi. Continued controversy.

The histopathologic criteria used in the diagnosis of dysplastic nevi have been a source of controversy, as has the clinical significance of these lesions. Several dermatopathologists noted for their work on dysplastic nevi were asked to contribute responses to questions regarding the architectural and cytological criteria used to classify a melanocytic nevus as dysplastic, the terminology used to describe these lesions, and the role of dysplastic nevi as precursors of melanoma. Although no consensus has been reached regarding the cytologic features required for diagnosis of dysplastic nevi, there is substantial agreement regarding the architectural features of these lesions.
