Dermatofibroma looks dermoscopically different on trunk versus extremities.

Background: Several dermoscopic patterns have been described in dermatofibroma (DF), but little is known about morphologic features of DF in different anatomic locations. The aim of this study was to evaluate the association between the dermoscopic pattern of DF and the anatomic location.

Methods: We conducted a retrospective observational study of 169 DF that were evaluated for the presence of dermoscopic structures and patterns.
