皮肤镜检查是一种非侵入性和成本有效的成像技术,可增强肿瘤性和非肿瘤性皮肤病的临床检查。最近,已经开发了基于反射/吸收和激发荧光原理的新型皮肤镜技术。然而,关于它们的应用的全面数据是稀疏的,和术语不一致。在这次系统审查中,我们讨论了紫外(UV)成像的原理,并提出了基于光谱特征和信号采集的分类,以及讨论的记录和潜在的临床应用,检查期间的安全措施,以及与反射和荧光皮肤镜检查相关的局限性。根据PRISMA指南,截至2023年12月2日,在PubMed医疗数据库中进行了文献检索。28篇论文符合这篇综述的范围,尽管还包括了其他相关文章,以提供有关所选术语的更广泛的背景,所描述的发色团,亚紫外线/紫外线的安全性,和发光器件的法规。紫外线和亚紫外线皮肤镜检查,根据发射波长和信号采集过程(反射率与荧光)分为不同的方法,通过优化黑色素瘤的安全裕度来增强常规皮肤镜检查,促进肿瘤复发的早期检测,并增强非肿瘤条件下的可视化,包括色素沉着症,intertrigo,丘疹性脱屑性皮肤病,和超越。这篇综述强调了这些技术的局限性,包括难以区分黑色素和血红蛋白,评估不平坦表面的挑战,和文物。虽然紫外线皮肤镜检查是传统皮肤镜检查的补充,临床医生应该意识到他们的特殊性,神器,局限性,和安全问题,以优化其诊断准确性并确保患者的安全。
Dermatoscopy is a non-invasive and cost-efficient imaging technique augmenting clinical examination in neoplastic and non-neoplastic dermatoses. Recently, novel dermatoscopic techniques based on principles of reflectance/
absorption and excited fluorescence have been developed. However, comprehensive data on their applications are sparse, and terminology is inconsistent. In this systematic
review, we addressed the principles of ultraviolet (UV) imaging and proposed categorization based on spectral characteristics and signal acquisition, as well as discussed documented and potential clinical applications, safety measures during examination, and limitations associated with reflectance and fluorescence dermatoscopy. A literature search was conducted in the PubMed medical database until 2 December 2023 according to PRISMA guidelines, and 28 papers fit the scope of this
review, whereas additional relevant articles were included to provide broader context regarding the chosen terminology, chromophores described, safety of sub-UV/UV, and regulations for light-emitting devices. UV and sub-UV dermatoscopy, categorized into different methods on the basis of the emitted wavelength and signal acquisition process (reflectance versus fluorescence), augment conventional dermatoscopy by optimizing safety margins in melanoma, facilitating early detection of tumor recurrence, and enhancing visualization in non-neoplastic conditions, including pigmentation disorders, intertrigo, papulo-desquamative dermatoses, and beyond. The
review highlights the limitations of these techniques, including difficulty in differentiating melanin from hemoglobin, challenges in evaluating uneven surfaces, and artifacts. Although UV dermatoscopy complements conventional dermatoscopy, clinicians should be aware of their peculiarities, artifacts, limitations, and safety concerns to optimize their diagnostic accuracy and ensure patient\'s safety.
