Lichen planopilaris (LPP) is a scarring alopecia seen classically in older Caucasian women. Frontal fibrosing alopecia (FFA) is a distinct disease that shares the histologic and trichoscopic features of LPP but differs in its clinical presentation in that it involves the frontal scalp and occasionally the eyelashes and eyebrows of older Caucasian women. Several recent studies have described a link between FFA and the use of sunscreen. Here we report a case of LPP arising in the part line of the scalp of a woman with a history of long-term daily application of spray-on sunscreen to the hair part line.
扁平苔藓性毛发角化病(LPP)是一种瘢痕性脱发,常见于老年白人女性。额部纤维性脱发(FFA)是一种独特的疾病,具有LPP的组织学和毛发镜特征,但其临床表现有所不同,它累及老年白人女性的额部头皮,偶尔也累及睫毛和眉毛。最近的几项研究描述了FFA与使用防晒霜之间的联系。在此,我们报告一例LPP病例,发生在一名有长期每日在头皮分缝处喷洒防晒霜病史的女性头皮分缝处。
