Alopecia areata (AA) is an autoimmune nonscarring alopecia that has variable clinical patterns, most commonly patchy disease. We report a case of AA with unusual involvement of the frontal hairline, mimicking frontal fibrosing alopecia (FFA), a form of scarring alopecia. Dermoscopic findings and response to treatment favored a diagnosis of AA. These findings highlight the major role of trichoscopy as well as the importance of including AA in the differential diagnosis for FFA.
斑秃（AA）是一种自身免疫性非瘢痕性脱发，有多种临床模式，最常见的是斑片状脱发。我们报告一例斑秃患者，其额发际线出现异常受累，类似瘢痕性脱发的一种形式——额部纤维性脱发（FFA）。皮肤镜检查结果及对治疗的反应支持斑秃的诊断。这些发现突出了毛发镜检的重要作用以及在FFA鉴别诊断中纳入AA的重要性。
