Lichen sclerosus (LS) is a rare and chronic autoimmune disease, and extragenital LS is particularly challenging to diagnose in children. Histopathology is the gold standard for diagnosis. Dermoscopy is a useful tool when follicular plugs (FP) are observed, though FP are sometimes hard to recognize. The ink test may provide a useful technique to enhance FP visualization and support a diagnosis of extragenital LS, thereby avoiding diagnostic delays or biopsy.
硬化性苔藓（LS）是一种罕见的慢性自身免疫性疾病，外阴 LS 在儿童中尤其难以诊断。组织病理学是诊断的金标准。当观察到毛囊塞（FP）时，皮肤镜检查是一种有用的工具，尽管 FP 有时很难识别。墨水试验可能是一种有用的技术，可以增强 FP 的可视化，支持外阴 LS 的诊断，从而避免诊断延迟或活检。
