Comment on “Diagnostic accuracy of ex vivo fluorescence confocal microscopy for Mohs surgery of basal cell carcinomas: A prospective study on 753 margins”

Abstract

We read with interest the paper by Longo C. et al.¹ regarding the diagnostic accuracy of ex vivo fluorescence confocal microscopy (FCM) for Mohs surgery (MMS) of basal cell carcinomas and we appreciated the potential of this imaging tool. Nevertheless, we would like to point out some issues regarding the use of MMS reported in the case series.

As showed in picture 2, standard vertical sections were cut and stained according to the "perimeter technique" (PT) in contrast with the principles of MMS consisting in cutting horizontal sections in order to get a proper peripheral and margin control.
