New observations of intraoperative dermoscopic features of the nail matrix and bed in longitudinal melanonychia

Abstract

Histopathological findings that differ from the patterns previously reported were found. An irregular pattern may also be seen in benign melanocytic nevi such as subungual blue nevus. A globular pattern may be defined as a new pattern corresponding to melanophages only. Additional dermoscopic and histopathological images should be shared to facilitate the development of further understanding and the standardization of the intraoperative dermoscopy of LM.
