ABSTRACT
Purpose: Even though Miescher’s nevus (MN) is very common in general population, little is known about
the validity of dermoscopic criteria to differentiate it from other papulonodular lesions located on the head
and neck. The aim of this study is to evaluate the dermoscopic findings of Miescher nevi (MNs) on the
head and neck in patients aged ≥40 years.
Material and Methods: In this descriptive cross-sectional study, a total of 170 MNs in 94 patients were
evaluated by using polarized light dermoscopy. Frequencies of dermoscopic findings in MNs were
determined using Statistical Package for Social Sciences for Windows 15.0.
Results: The most frequently detected dermoscopic pattern in MNs was globular pattern (64.5%), less
often homogeneous (32.4%) or cobblestone pattern (2.9%). Globules were observed in 75.3% of MNs and
dots were seen in 12.4%. They frequently had skin-colored (87.1%) or light-brown (49.4%) homogeneous
structureless areas. Elongated comma vessels (47.1%) were the most common vascular findings.
Although comma vessels (33.5%) and linear vessels (4.7%) were also observed, 11.2% of MNs presented
“tristar vessels” (a newly described vascular pattern) that showed regular ‘tristar like ramifications’ in the
distal part of the vessels.
Conclusion: Firstly identified “tristar vessel pattern” is a dermoscopic description of MNs that can be a
useful clue to differential diagnosis.
