Scalp discoid lupus erythematosus in Caucasians is still a rare disease with a variable clinical presentation. Its dermoscopic characteristics are poorly described in literature, especially in the white population. The aim of this review was to critically analyze published papers on this topic and summarize relevant features.
A comprehensive search for eligible articles was conducted in the databases of MEDLINE/PubMed. Results were analyzed following dermoscopic patterns such as follicular openings, hair shafts, perifollicular surface, and vessel pattern.
The most representative features appeared the absence of follicular openings and the presence of follicular keratotic plugs, along with yellow-brown and red dots. In long-lasting lesions with chronic stage, trichoscopy showed the absence of follicular openings, white or milky red cicatricial patches, white and brown structureless areas, and thick arborizing vessels.
白种人中的头皮盘状红斑狼疮仍然是一种罕见疾病，临床表现多样。其皮肤镜特征在文献中描述较少，尤其是在白人群体中。本综述的目的是批判性地分析关于该主题的已发表论文，并总结相关特征。
在MEDLINE/PubMed数据库中对符合条件的文章进行了全面检索。根据毛囊开口、毛干、毛囊周围表面和血管形态等皮肤镜模式对结果进行了分析。
最具代表性的特征是毛囊开口缺失、毛囊角化栓存在，以及黄棕色和红色小点。在处于慢性期的长期病变中，毛发镜检查显示毛囊开口缺失、白色或乳红色瘢痕性斑块、白色和棕色无结构区域以及粗大的树枝状血管。
