Dermoscopy is gaining appreciation in the spectrum of non-neoplastic skin conditions, especially papulosquamous and granulomatous dermatoses. However, the use of dermoscopy in such diseases has not yet acquired a standard role in daily practice due to the lack of a structured approach as well as possible pitfalls limiting its accuracy.
A descriptive analysis of the most common limitations/pitfalls described in the literature regarding dermoscopy of non-neoplastic dermatoses was performed, also providing possible tips to deal with them.
The following items were analyzed: "two-step" dermoscopic procedure and basic dermoscopic parameters in non-neoplastic dermatoses, uniform dotted vessels in dermatoses other than psoriasis, pseudo-Wickham striae, yellow sero-crusts in non-eczematous dermatoses, peripheral scaling collarette in conditions other than pityriasis rosea, orange areas in non-granulomatous dermatoses, and dermoscopic variability of Grover disease according to histological subtype.
Dermoscopy is candidate to become a relevant part of diagnostic approach to non-neoplastic dermatoses, yet only the use of a systematic/validated methodology and the in-depth knowledge of possible pitfalls may optimize its use in this field.
皮肤镜检查在非肿瘤性皮肤疾病的范围内得到了认可，特别是在丘疹鳞屑性和肉芽肿性皮肤病中。然而，由于缺乏结构化的方法以及可能限制其准确性的潜在陷阱，皮肤镜检查在这些疾病中的应用尚未在日常实践中获得标准作用。
对文献中描述的关于非肿瘤性皮肤病皮肤镜检查的最常见的局限性/潜在陷阱进行了描述性分析，并提供了可能的处理建议。
分析了以下内容：非肿瘤性皮肤病的“两步”皮肤镜检查程序和基本皮肤镜参数、除银屑病以外的皮肤病中的均匀点状血管、假性威克姆纹、非湿疹性皮肤病中的黄色血清结痂、除玫瑰糠疹以外的疾病中的周边鳞屑领、非肉芽肿性皮肤病中的橙色区域，以及根据组织学亚型的格罗弗病的皮肤镜检查变异性。
皮肤镜检查有望成为非肿瘤性皮肤病诊断方法的重要组成部分，但只有使用系统/经过验证的方法和深入了解可能存在的陷阱，才能优化其在该领域的应用。
