Background: Teledermatology is employed in the diagnosis and follow-up of skin cancer and its use was intensified during and after the COVID-19 pandemic. At the same time, demographic changes result in an overall increase in non-melanoma skin cancer and skin precancerous lesions. The aim of this study was to elucidate the role of teledermatology in comparison to conventional face-to-face dermatology for such lesions and determine the advantages and limitations of this workflow for patients and physicians. Methods: Research was performed using relevant keywords in MEDLINE and CENTRAL. Relevant articles were chosen following a predetermined standardized extraction form. Results: Diagnostic accuracy and interrater/intrarater agreement can be considered comparable—although lower—than in-person consultation. Improvement of particular features such as image quality, medical history availability, and teledermoscopy can further increase accuracy. Further aspects of limitations and advantages (mean time-to-assessment, time-to-treatment, cost-effectiveness) are discussed. Conclusions: Teledermatology has comparable diagnostic accuracy with face-to-face dermatology and can be utilized both for the effective triage of non-melanocytic epithelial tumors and precancerous lesions, as well as the follow-up. Easy access to dermatologic consultation with shorter mean times to diagnostic biopsy and/or treatment coupled with cost-effectiveness could compensate for the lower sensitivity of teledermatology and offer easier access to medical care to the affected populations.
背景：远程皮肤病学被用于皮肤癌的诊断与随访，在COVID-19大流行期间及之后其应用显著加强。与此同时，人口结构变化导致非黑色素瘤皮肤癌及皮肤癌前病变总体发病率上升。本研究旨在阐明远程皮肤病学相较于传统面对面诊疗在此类病变中的作用，并分析该工作流程对患者和医生的优势与局限。 方法：通过MEDLINE和CENTRAL数据库使用相关关键词进行文献检索，依据预设标准化提取表筛选相关文献。 结果：远程皮肤病学的诊断准确率及观察者间/观察者内一致性虽略低于面诊，但仍具有可比性。通过提升图像质量、完善病史信息获取及结合远程皮肤镜技术可进一步提高诊断准确性。研究还讨论了其他限制因素与优势（如平均评估时间、治疗等待时间、成本效益等）。 结论：远程皮肤病学与面诊具有相当的诊断准确性，可有效用于非黑素细胞性上皮肿瘤及癌前病变的分诊与随访。该模式能提供便捷的皮肤科咨询途径，缩短诊断性活检和/或治疗的平均等待时间，兼具成本效益优势，这些特点可弥补其敏感度相对较低的不足，为患者群体提供更便捷的医疗服务。
