“…10 It is not known how long these "atypical" changes persist in traumatized nevi. 8,9 There are very few studies about the dermoscopic changes caused by unintentional trauma in melanocytic nevi. 19,20 Yoshida and colleagues reported the case of a 47year-old patient who presented with pigmentation in a starburst pattern after trauma in a nevus present since childhood.…”

“…It is not known how long these atypical histological changes persist in traumatized nevi, and their histological characteristics are believed to be similar to those of recurrent nevi. 8,9 Although trauma in melanocytic nevi is a common complaint, the dermoscopic changes caused by trauma are not very clear, and their recognition may prevent unnecessary surgical procedures in some cases. The aim of this study is to evaluate dermoscopic changes in nevi traumatized in a controlled manner through dermabrasion.…”

BACKGROUND Melanocytic nevi submitted to trauma can undergo clinical, dermoscopic, and even histological changes, making it difficult to differentiate them from a melanoma. OBJECTIVE The aim of this study is to evaluate the dermoscopic changes of traumatized nevi after dermabrasion. METHODS Dermoscopic images of acquired melanocytic nevi were compared before and 4 weeks after half of their area had undergone dermabrasion. RESULTS The sample consisted of 50 lesions from 15 patients. The homogeneous pattern was the most frequent, followed by the reticular, cobblestone, and globular patterns. After dermabrasion, nearly half of the lesions (46%) became dermatoscopically asymmetric. Among all lesions, structureless areas, dotted vessels and erythema were the most frequent new dermoscopic structures. CONCLUSION Trauma after dermabrasion may induce significant dermoscopic changes in melanocytic nevi. Although the global pattern did not change, most of the lesions became asymmetric, with the appearance or fading of dermoscopic structures and colors. A history of recent trauma should be investigated when evaluating pigmented lesions.
