Can Dermoscopy Be Used to Predict if a Melanoma Is In Situ or Invasive?

ABSTRACT:

Background

The preoperative prediction of whether melanomas are invasive or in situ can influence initial management.

Objectives

This study evaluated the accuracy rate, interobserver concordance, sensitivity and specificity in determining if a melanoma is invasive or in situ, as well as the ability to predict invasive melanoma thickness based on clinical and dermoscopic images.

Methods

In this retrospective, single-center investigation, 7 dermatologists independently reviewed clinical and dermoscopic images of melanomas to predict if they were invasive or in situ and, if invasive, their Breslow thickness. Fleiss' and Cohen's kappa (κ) were used for interobserver concordance and agreement with histopathological diagnosis.
