Central white scarlike patch: a dermatoscopic clue for the diagnosis of dermatofibroma

In this study, dermatoscopic examination of 24 dermatofibromas was performed to evaluate specific dermoscopic criteria. A central white scarlike patch was appreciable in 22 of 24 lesions, whereas 20 of 24 dermatofibromas exhibited a delicate pigment network at the periphery. This stereotypical dermatoscopic finding allowed the diagnosis of dermatofibroma in most instances. (J Am Acad Dermatol 2000;43:1123-5.).
