Discoid lupus erythematosus (DLE) is the most common type of chronic cutaneous lupus erythematosus. It is more frequent in adult women, particularly black race. Scalp DLE has an earlier onset and a more severe clinical course in black patients compared to Caucasians. Nevertheless, studies on this population remain scarce. The aim of this study was to review the literature and summarize the most frequent trichoscopic findings of scalp DLE among patients with a higher phototype. The main trichoscopic findings of DLE on black scalp are interruption of the honeycomb pattern, reduction, or absence of pinpoint white dots, keratotic follicular plugs and peripilar casts, blue-gray dots in a speckled pattern, and large tortuous arboriform vessels. Knowledge of these and other changes enables an early diagnosis of these individuals, preventing cicatricial sequelae and reducing its impact on quality of life.
盘状红斑狼疮（DLE）是慢性皮肤型红斑狼疮最常见的类型。在成年女性中更为常见，尤其是黑人种族。与白种人相比，黑人患者头皮DLE发病更早，临床病程更严重。然而，针对这一人群的研究仍然很少。本研究的目的是回顾文献，总结光型较高的患者中头皮DLE最常见的皮肤镜表现。黑人头皮DLE的主要皮肤镜表现为蜂窝状图案中断、点状白点减少或缺失、角化性毛囊栓和毛囊周痂、散在分布的蓝灰色点以及粗大迂曲的树枝状血管。了解这些及其他变化有助于对这些个体进行早期诊断，预防瘢痕后遗症并减轻其对生活质量的影响。
