Linear scleroderma en coup de sabre (LSCS) is the most common form of morphea on the scalp and its trichoscopic features have not been described yet. We report 2 adult women with LSCS with distinct dermoscopic findings. They both had an atrophic well-defined linear patch of alopecia on the frontotemporal scalp. Dermoscopy showed loss of follicular openings on a whitish skin surface; scattered black dots, broken hairs, and pili torti; and short thick linear and branching tortuous vessels on the periphery of the lesion. Pathology confirmed the diagnosis of LSCS in the 2 cases. This description of dermoscopic features in LSCS on the scalp may help in the early diagnosis of the disease.
线状硬皮病（en coup de sabre型，LSCS）是头皮部硬斑病最常见的类型，其皮肤镜特征尚未见报道。我们报告2例成年女性LSCS患者，有独特的皮肤镜表现。她们在额颞部头皮均有萎缩性、边界清晰的线状脱发斑。皮肤镜检查显示白色皮肤表面毛囊开口缺失；散在黑点、断发及扭曲发；病变周边有短而粗的线状及分支状迂曲血管。病理检查确诊了这2例LSCS。头皮部LSCS皮肤镜特征的描述可能有助于该病的早期诊断。
