[Standardized epiluminescent microscopy for differentiating melanocytic and non-melanocytic pigment nevi].

Abstract

Epiluminescent microscopy (ELM) has been widely accepted as a non-invasive, rapid technique for the differentiation of pigmented skin lesions. The method is valuable for distinguishing melanocytic and non-melanocytic tumors, as well as for identifying malignant melanoma. Due to great morphological variability of pigmented lesions considerable experience is required. Based on a morphological analysis of 600 pigmented skin lesions, a diagnostic procedure was developed that permits a reproducible description and diagnosis of a given lesion and facilitates training in ELM.
