Reflectance confocal microscopy (RCM) is a non\u2010invasive imaging modality that enables in\u00a0vivo visualization of the skin at the cellular level, allowing for adequate estimation of LM\/LMM margins.<\/jats:p><\/jats:sec><jats:sec><jats:title>Objectives<\/jats:title><jats:p>We aimed to perform a systematic review and meta\u2010analysis evaluating RCM's performance compared with histopathology in margin mapping of LM\/LMM.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We searched MEDLINE, Embase, Cochrane, and <jats:ext-link xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" xlink:href=\"http:\/\/clinicaltrials.gov\">Clinicaltrials.gov<\/jats:ext-link> for studies published until July 2023, assessing RCM diagnostic accuracy for presurgical LM\/LMM margin delineation.
