Dermoscopy versus reflectance confocal microscopy for the diagnosis of lentigo maligna

BACKGROUND:
Several dermoscopic and in vivo reflectance confocal microscopy (RCM) diagnostic criteria of lentigo maligna (LM)/lentigo maligna melanoma (LMM) have been identified. However, no study compared the diagnostic accuracy of these techniques.

OBJECTIVE:

We evaluated the diagnostic accuracy of dermoscopy and RCM for LM/LMM using a holistic assessment of the images.

METHODS:

223 facial lesions were evaluated by 21 experts. Diagnostic accuracy of the clinical, dermoscopic and RCM examination were compared. Inter-investigator variability and confidence level in the diagnosis were also evaluated.

RESULTS:

Overall diagnostic accuracy of the two imaging techniques was good (area under the curve of the sROC function: 0.89). RCM was more sensitive (80%, versus 61%) and less specific (81% versus 92%) than dermoscopy for LM/LMM. In particular RCM showed a higher sensitivity for hypomelanotic and recurrent LM/LMM. RCM had a higher inter-investigator agreement and a higher confidence level in the diagnosis than dermoscopy.

CONCLUSION:

RCM and dermoscopy are both useful techniques for the diagnosis of facial lesions and in particular LM/LMM. RCM is particularly suitable for the identification of hypomelanotic and recurrent LM/LMM. This article is protected by copyright. All rights reserved.
