BackgroundCentral white scarlike patch and a delicate pigment network at the periphery is the typical appearance of dermatofibromas on dermoscopy.ObjectiveWe aimed to analyze the different dermoscopic appearances of dermatofibromas.MethodsFifty-two dermatofibromas with dermoscopic features different from the classic type, which were detected between May 2003 and July 2005, were evaluated.ResultsGlobules in the scarlike area (38.5%), linear/irregular crypts (26.9%), lentigo-like reticular pigmentation (23%), homogeneous blue-gray pigmentation (5.9%), and erythematous homogeneous area surrounding the white patch (3.8%) were the patterns observed. In addition, dermoscopic features of an atrophic variant of dermatofibroma are described, which was seen in one lesion (1.9%).LimitationsNone.ConclusionDermatofibromas have various dermoscopic features. Among them, “linear, irregular crypts” is not unusual and is described in this study. Homogeneous bluish pigmentation on dermoscopy may be a possible clue for the diagnosis of hemosiderotic variants of dermatofibromas.
