The 2016 International League of Dermatological Societies' revised glossary for the description of cutaneous lesions

Abstract

Background: In order to facilitate effective communication in dermatology, a clearly defined glossary with precise descriptions is essential. The International League of Dermatological Societies' (ILDS) ‘Glossary of basic dermatology lesions’ was first published in 1987. A quarter of a century later, the ILDS made the decision to revise and expand this nomenclature. Objectives: Revision and expansion of an international nomenclature for the description of cutaneous lesions. Methods: The ILDS nominated a committee on nomenclature. Based on a review of the literature and major textbooks, the committee assembled a list of terms and definitions. National member societies of the ILDS were then invited to participate in a Delphi voting exercise (two rounds for basic descriptive terms, one round for additional terms). The committee reviewed and consolidated comments and consented the final version. Results: The revised and expanded version of the ILDS nomenclature includes 13 basic terms and over 100 additional descriptive terms. Forty-six and then 34 national member societies participated in the first and second voting rounds, respectively. Conclusions: A unifying nomenclature is crucial for effective communication among dermatologists and those who care for skin diseases. The next step will be a roll-out programme to national member societies of the ILDS that will include translations into languages other than English and adaptations reflecting local circumstances.
