Abstract :Purpose: Although it is very common in people over 30 years old, little is known about the validity of dermoscopic criteria to differentiate Miescher’s nevus insert ignore into journalissuearticles values(MN); from other papulonodular lesions located on the head and neck. The aim of this study is to evaluate the dermoscopic findings in MN on the head and neck in patients over 40 years by using dermoscopy. Methods: In this descriptive cross-sectional study 170 MN were evaluated by using polarized light dermoscopy. frequencies of dermoscopic findings in MN were determined using Statistical Package for Social Sciences for Windows 15.0. Results: The most frequently detected dermoscopic pattern in MN was globular pattern insert ignore into journalissuearticles values(64.5%);, less often homogeneous insert ignore into journalissuearticles values(32.4%); or cobblestone pattern insert ignore into journalissuearticles values(2.9%);. Globules were observed in 75.3% of MN and dots were seen in 12.4%. They frequently had skin-colored insert ignore into journalissuearticles values(87.1%); or light-brown insert ignore into journalissuearticles values(49.4%); homogeneous structureless areas. Elongated comma vessels insert ignore into journalissuearticles values(47.1%); were the most common vascular findings. Although comma vessels insert ignore into journalissuearticles values(33.5%); and linear vessels insert ignore into journalissuearticles values(4.7%); were also observed, 11.2% of MN presented “tristar vessels” insert ignore into journalissuearticles values(a newly described vascular pattern); that showed regular ‘tristar like ramifications’ in the distal part of the vessels. Conclusions: Firstly identified “tristar vessel pattern” is a dermoscopic description of MN that can be a useful clue to differential diagnosis.
