Acquired trichorrhexis nodosa is an uncommon hair disorder, defined as a cuticle response to extrinsic or environmental insults, such as certain chemical agents. In the following report, we present a clinical case of acquired trichorrhexis nodosa and make a critical comparison by trichoscopy, optical microscopy, and scanning electron microscopy. Some diagnostic tools can provide high quality information, but their high cost and low access make them an inconvenient option. When comparing the cost-benefit ratio of each one, we conclude that acquired trichorrhexis nodosa can be easily diagnosed with a careful clinical history and examination using a dermatoscope with non-polarized light.
获得性结节性脆发症是一种罕见的毛发疾病，定义为角质层对外源性或环境性损伤（如某些化学制剂）的反应。在以下报告中，我们展示了一例获得性结节性脆发症的临床病例，并通过毛发镜检查、光学显微镜检查和扫描电子显微镜检查进行了关键比较。一些诊断工具可以提供高质量的信息，但它们成本高昂且难以获得，这使得它们成为一种不太方便的选择。在比较每种工具的成本效益比时，我们得出结论，通过仔细询问临床病史并使用非偏振光的皮肤镜进行检查，可以轻松诊断获得性结节性脆发症。
