Abstract

Central centrifugal cicatricial alopecia (CCCA) is a common and progressive form of lymphocyte predominant scarring alopecia which impacts negatively on the quality of life of those affected. It is seen more commonly in women of African descent with prevalence ranging from 2.7% to 5.7%. Current postulates include genetic inheritance, with traction inducing hairstyling practices and hair chemicals as aggravating factors. Histology reveals a perifollicular lymphocytic inflammation of the lower infundibulum, premature desquamation of the inner root sheath, and fibrous connective tissue. Treatment remains challenging and is directed at suppressing and preventing the inflammation, thus aborting scarring, with surgical intervention reserved for those who have stable disease or absence of histological inflammation. Future research with more patient numbers, focusing on the genetics of CCCA may prove useful in order to fully understand the etiology, thus providing more effective treatments for CCCA.

摘要

中央离心性瘢痕性秃发(CCCA)是一种常见的、进行性的以淋巴细胞为主的瘢痕性秃发,对患者的生活质量有负面影响。它在非洲裔女性中更为常见,患病率在2.7%至5.7%之间。目前的推测包括遗传因素,牵引性发型和头发化学制品是加重因素。组织学显示漏斗下部毛囊周围淋巴细胞炎症、内根鞘过早脱屑和纤维结缔组织。治疗仍然具有挑战性,旨在抑制和预防炎症,从而避免瘢痕形成,手术干预仅适用于病情稳定或无组织学炎症的患者。未来针对更多患者的研究,聚焦于CCCA的遗传学,可能有助于全面了解病因,从而为CCCA提供更有效的治疗方法。
