■额叶纤维性脱发(FFA)是瘢痕性脱发的重要原因,主要见于绝经后女性,但有时见于绝经前女性和男性。尽管由于其组织病理学特征而被认为是扁平苔藓的变体,它具有独特的临床特征和关联,这使得它成为一个独特的实体。我们特此报告一系列来自印度东北部的FFA患者。
■本研究旨在分析FFA的临床和组织病理学特征。
我们回顾性分析了2013年4月至2023年2月在皮肤科门诊确诊的FFA病例的临床记录和组织病理学特征。
■总共21名患者,对2013年4月至2023年2月被诊断为FFA的患者进行了分析。其中,19名患者为女性,男女比例为9.5:1。研究人群的平均年龄为48.33岁。大多数患者来自绝经后年龄组(15/19女性,78.94%)。色素扁平苔藓(6,28.57%)是最常见的相关疾病,其次是雄激素性脱发和扁平苔藓(各2个,9.52%)。主要组织学特征为18例(85.71%)滤泡周围淋巴细胞浸润,其次是15例(71.42%)的基础卵泡角质形成细胞水肿变性和14例(66.66%)的黑色素失禁。
■我们的研究是来自印度东北部的第一项研究,重点是FFA的临床表现和组织病理学特征。此外,关于FFA的最新发展,我们的研究试图确定Tolkachjov等人提出的FFA患者诊断标准的临床意义.(2018),viz.国际FFA合作集团标准(2021年)。
UNASSIGNED: Frontal fibrosing alopecia (FFA) is an important cause of scarring alopecia seen mostly in post-menopausal women but sometimes in pre-menopausal women and men. Although considered a variant of lichen planopilaris due to its histopathological characteristics, it has distinct clinical features and associations, which make it a unique entity. We hereby report a series of patients with FFA from North-East India.
UNASSIGNED: This study aimed to analyse the clinical and histopathological characteristics of FFA.
UNASSIGNED: We retrospectively analysed clinical records and histopathological features of FFA cases diagnosed in the Dermatology Outpatient Department from April 2013 to February 2023.
UNASSIGNED: A total of 21 patients, who were diagnosed with FFA from April 2013 to February 2023, were analysed. Of these, 19 patients were female, with a male-to-female ratio of 9.5:1. The mean age of study population was 48.33 years. The majority of the patients were from the post-menopausal age group (15/19 females, 78.94%). Lichen planus pigmentosus (6, 28.57%) was the most commonly associated disease, followed by androgenetic alopecia and lichen planopilaris (2 each, 9.52%). The main histological features noted were perifollicular lymphocytic infiltrate in 18 (85.71%), followed by hydropic degeneration of basal follicular keratinocytes in 15 (71.42%) and melanin incontinence in 14 (66.66%) patients.
UNASSIGNED: Our study is the first study from North-East India focusing on the clinical presentation and histopathological characteristics of FFA. Furthermore, with respect to the recent development in FFA, our study attempted to determine the clinical significance of the proposed criteria for the diagnosis of FFA patients by Tolkachjov et al. (2018), viz. International FFA Cooperative Group Criteria (2021).
