The International Study Group on Melanonychia was founded in 2007 and currently has 30 members, including nail experts and dermatopathologists with special expertise in nails. The need for common definitions of nail plate dermoscopy was addressed during the Second Meeting of this Group held in February 2008. Prior to this meeting and to date (2010) there have been no evidence-based guidelines on the use of dermoscopy in the management of nail pigmentation.enDermoscopyMelanomaNailsNail diseases600 - Technology::610 - Medicine & healtharticle10.7892/boris.455402373969910.1590/S0365-05962013000200029
