Dermoscopy Improves the Diagnostic Accuracy of Melanomas Clinically Resembling Seborrheic Keratosis: Cross-Sectional Study of the Ability to Detect Seborrheic Keratosis-Like Melanomas by a Group of Dermatologists with Varying Degrees of Experience.

Background: Malignant melanomas mimicking seborrheic keratosis (SK-like MMs) carry the risk of delayed diagnosis and inadequate treatment. The value of dermoscopy to improve the correct detection of these mimickers has not been previously studied.

Objective: To evaluate the diagnostic accuracy of clinically SK-like MMs with and without dermoscopy.
