头皮病理活检在脱发疾病诊疗中的相关应用

Application of scalp pathological biopsy in diagnosis and treatment of alopecia

脱发是皮肤科门诊中常见的疾病。尽管一些毛发疾病并不依赖病理检查,随着科技水平的发展,许多新型无创毛发及头皮检测仪器,如皮肤镜、毛发扫描仪、皮肤CT等,它们在毛发疾病的诊疗中的作用日益被重视,但病理检查的作用仍然无可替代。考虑到毛发疾病的特殊性,毛发病理不同于普通的皮肤病理,其主要表现在头皮活检时的取材部位、活检方式、切片方式、读片内容等方面。本文就头皮病理活检如何在脱发疾病中的诊疗中发挥作用作一综述。

Alopecia is a common disease in dermatologic clinics.The diagnosis of some hair diseases does not rely on pathological examinations,and with the development of science and technology, the role of many new non-invasive detection instruments,such as dermoscopy,hair scanners and skin CT,is increasingly valued in the diagnosis and treatment of hair diseases.However,the role of pathological examination is still irreplaceable.Because of the particularity of hair diseases,hair pathology differs from common skin pathology in the aspects of scalp biopsy sites,biopsy methods and techniques,tissue-slicing methods and pathological report content.This review systematically discusses the role of scalp pathological biopsy in the diagnosis and treatment of alopecia.
