Abstract

Introduction: Plantar and palmar melanocytic nevi constitute a distinct subtype of nevi, characterized by unique dermoscopic patterns. Currently, limited research has focused on the dermoscopic features of plantar and palmar melanocytic nevi in children.

Objective: To characterize the dermoscopic features of congenital and acquired plantar and palmar melanocytic nevus in children and to evaluate the diagnostic contribution of dermoscopy.

Methods: A retrospective analysis was conducted on 180 pediatric patients initially clinically diagnosed with plantar and palmar nevi. Dermoscopic evaluation was performed using Dermo-II system, followed by histopathological confirmation.

Results: Histopathology confirmed 172 plantar and palmar nevi and 8 cases of black heel. The most prevalent dermoscopic patterns were the parallel furrow pattern (54.65%), fibrillar pattern (22.09%), and reticular pattern (10.47%). No significant differences were observed between congenital and acquired nevi. Dermoscopy achieved 100% concordance with histopathology, significantly higher than clinical diagnosis alone (95.56%; p = 0.0075).

Conclusion: Dermoscopy is a reliable, non-invasive adjunct for diagnosing pediatric plantar and palmar nevi, potentially reducing unnecessary excisions.

儿童足底及掌黑素细胞痣的皮肤镜特征：儿童足底及掌黑素细胞痣的皮肤镜检查。

足底和掌部黑色素细胞痣是一种独特的痣亚型，具有独特的皮肤镜模式。目前，关于儿童足底和掌部黑素细胞痣的皮肤镜特征研究有限。目的：探讨儿童先天性和后天性足底掌黑素细胞痣的皮肤镜特征，评价皮肤镜的诊断价值。方法：对180例临床诊断为足底掌痣的患儿进行回顾性分析。使用Dermo-II系统进行皮肤镜评估，然后进行组织病理学确认。结果：组织病理学证实足底及掌部痣172例，黑跟8例。最常见的皮镜型为平行沟型（54.65%）、纤原型（22.09%）和网状型（10.47%）。先天性痣与后天性痣无明显差异。皮肤镜检查与组织病理学的符合率为100%，明显高于单纯临床诊断（95.56%,p = 0.0075）。结论：皮肤镜检查是一种可靠的、无创的诊断小儿足底和掌痣的辅助手段，可以减少不必要的手术。

期刊介绍： Skin Research and Technology is a clinically-oriented journal on biophysical methods and imaging techniques and how they are used in dermatology, cosmetology and plastic surgery for noninvasive quantification of skin structure and functions. Papers are invited on the development and validation of methods and their application in the characterization of diseased, abnormal and normal skin. Topics include blood flow, colorimetry, thermography, evaporimetry, epidermal humidity, desquamation, profilometry, skin mechanics, epiluminiscence microscopy, high-frequency ultrasonography, confocal microscopy, digital imaging, image analysis and computerized evaluation and magnetic resonance. Noninvasive biochemical methods (such as lipids, keratin and tissue water) and the instrumental evaluation of cytological and histological samples are also covered. The journal has a wide scope and aims to link scientists, clinical researchers and technicians through original articles, communications, editorials and commentaries, letters, reviews, announcements and news. Contributions should be clear, experimentally sound and novel.
