Diagnostic Performance of Dermoscopy for Distinguishing Early Melanomas and Intermediate Melanocytic Lesions From Low-Grade Dysplastic Nevi.

ABSTRACT:

Background

Early melanomas, dysplastic melanocytic nevi, and melanocytic tumours of uncertain malignant potential (MELTUMPs) reveal similar clinic and dermoscopic findings leading to underdiagnosis of malign lesions or unnecessary excision of benign ones. High-grade dysplastic nevi and MELTUMPs in the intermediate category should be recognized and completely excised.

Objectives

We evaluated the diagnostic performance of pattern analysis, ABCD rule, colour, architecture, symmetry, and homogeneity algorithm, melanoma-specific structures and asymmetry of dermoscopic features in distinguishing early melanomas, high-grade dysplastic nevi, and MELTUMPs from low-grade dysplastic nevi.

Methods

We retrospectively assessed dermoscopic images blindly to the histopathological dia
