    (2023) Navarrete-Dechent, Cristian; Cordova, Miguel; Aleissa, Saud; Liopyris, Konstantinos; Dusza, Stephen W.; Kose, Kivanc; Busam, Klaus J.; Hollman, Travis; Lezcano, Cecilia; Pulitzer, Melissa; Chen, Chih-Shan J.; Lee, Erica H.; Rossi, Anthony M.; Nehal, Kishwer S.
    Background: Lentigo maligna/lentigo maligna melanoma (LM/LMM) can present with subclinical extension that may be difficult to define preoperatively and lead to incomplete excision and potential recurrence. Preliminarily studies have used reflectance confocal microscopy (RCM) to assess LM/LMM margins.

    Background There is lack of uniformity in reflectance confocal microscopy (RCM) terminology. Objective To establish expert consensus on a standardized set of RCM terms that describe non-melanocytic lesions (NML). Methods We invited RCM experts to participate in a Delphi-consensus study. Fifty-nine RCM descriptors were extracted from a previous systematic review on RCM terminology for describing NML. Of these, 35 items were presented as 4 groups of synonymous terms and 24 items as single, non-synonymous terms. For the first round, an agreement threshold was set at >70%. Participants could also propose new terms. Terms with ≤70% agreement and newly proposed terms were carried over to the next round. For subsequent rounds, agreement threshold was set at >50%. Results The study was conducted between June 2021 and May 2023. Forty-two of 44 (95%) invited experts participated. Three iterative Delphi rounds were completed, resulting in a consensus list of 36 terms, including 32 synonymous- and 4 non-synonymous- terms for describing NML. Limitations Only experts were included. We did not evaluate definitions of terms in the study. Conclusions We propose a simplified list of RCM terms, vetted by RCM experts, for describing and diagnosing NML. Uniform terminology could benefit clinical practice, research, and education.
