Dermoscopic findings of spitz nevus in Koreans: A case series and single-center experience

Background: Dermoscopy is a noninvasive magnification technique that increases the diagnostic accuracy of clinical evaluation by a dermatologist. The characterization of Spitz nevus via dermoscopy is useful for dermatologists in the differential diagnosis of skin tumors. Objective: The purpose of this study was to investigate the dermoscopic features of Spitz nevus in Koreans. Methods: We examined 18 patients with Spitz nevus using dermoscopy. We determined the frequency of specific features revealed by dermoscopy across the single center 15 Korean patients. Results: A total of 21 of Spitz nevi were observed in 18 patients. The common features of Spitz nevi revealed by dermoscopy were regular homogeneous pigmentation (38.1%), a typical pigmented Spitzoid pattern (28.6%), irregular homogeneous pigmentation (23.8%), regular streaks (23.8%), irregular streaks (23.8%), a superficial black network (23.8%), and a nonpigmented typical Spitzoid pattern (19.0%). Conclusion: Dermoscopy revealed specific features of Spitz nevus that can be utilized to evaluate and diagnose the lesions.
