Original articleStandardization of terminology in dermoscopy/dermatoscopy: Results of the third consensus conference of the International Society of Dermoscopy

BackgroundEvolving dermoscopic terminology motivated us to initiate a new consensus.ObjectiveWe sought to establish a dictionary of standardized terms.MethodsWe reviewed the medical literature, conducted a survey, and convened a discussion among experts.ResultsTwo competitive terminologies exist, a more metaphoric terminology that includes numerous terms and a descriptive terminology based on 5 basic terms. In a survey among members of the International Society of Dermoscopy (IDS) 23.5% (n = 201) participants preferentially use descriptive terminology, 20.1% (n = 172) use metaphoric terminology, and 484 (56.5%) use both. More participants who had been initially trained by metaphoric terminology prefer using descriptive terminology than vice versa (9.7% vs 2.6%, P < .001). Most new terms that were published since the last consensus conference in 2003 were unknown to the majority of the participants. There was uniform consensus that both terminologies are suitable, that metaphoric terms need definitions, that synonyms should be avoided, and that the creation of new metaphoric terms should be discouraged. The expert panel proposed a dictionary of standardized terms taking account of metaphoric and descriptive terms.LimitationsA consensus seeks a workable compromise but does not guarantee its implementation.ConclusionThe new consensus provides a revised framework of standardized terms to enhance the consistent use of dermoscopic terminology.
