Frontal fibrosing alopecia (FFA) is a progressive scarring alopecia of unknown etiology that classically presents with a band of hair loss along the frontotemporal scalp. We report a case of FFA involving a band of alopecia along the frontotemporal scalp extending into 2 symmetrical triangles along the parietal scalp reminiscent of the Greek letter upsilon (υ). Trichoscopy demonstrated loss of follicular ostia and peripilar casts. Histology demonstrated altered follicular architecture with decreased follicular density and focal perifollicular fibrosis with a lichenoid infiltrate. Both the trichoscopy and histology support a diagnosis of FFA.
额部纤维性秃发（FFA）是一种病因不明的进行性瘢痕性秃发，典型表现为额颞部头皮出现一条脱发带。我们报告一例FFA病例，其额颞部头皮的脱发带沿顶叶头皮延伸为两个对称的三角形，形似希腊字母υ（Upsilon）。毛囊镜检查显示毛囊口缺失和毛周角质栓。组织学检查显示毛囊结构改变，毛囊密度降低，局灶性毛囊周围纤维化伴苔藓样浸润。毛囊镜检查和组织学检查均支持FFA的诊断。
