: The umbilicus is a fibrous remnant located in the centre of the abdomen. Various entities may be encountered in this special anatomical location; however, little is known about their dermoscopic presentation. The aim of this study was to provide a comprehensive summary of existing evidence on dermoscopic features of umbilical lesions. : Studies assessing dermoscopic images of umbilical lesions were included in this study. No age, ethnicity or skin phototype restrictions were applied. Papers assessing lesions outside of the umbilical area, lacking dermoscopic images and/or dermoscopic description and not related to the topic were excluded. Embase, Medline and Cochrane Library were searched from inception to the end of May 2023. The Joanna Briggs Institute critical appraisal tools were used to evaluate the risk of bias of the selected studies. The quality and the level of evidence of included studies were assessed according to the Oxford 2011 Levels of Evidence. Thirty-four studies reporting a total of 39 lesions met the inclusion criteria and were included in qualitative analysis. : A qualitative synthesis of the following entities was performed: melanoma, nevi, basal cell carcinoma, fibroepithelioma of Pinkus, Sister Mary Joseph nodule, mycosis fungoides, dermatofibroma, endometriosis, epidermal cyst, granuloma, intravascular papillary endothelial hyperplasia, lichen planus, omphalolith, seborrheic keratosis, and syringoma. : Dermoscopy is a non-invasive technique that may be useful in the differential diagnosis of umbilical lesions. The main limitations of this study were lack of a high level of evidence in the studies and the lack of uniformity in applied dermoscopic terminology between included studies.
脐是位于腹部中央的纤维性残余物。在这个特殊的解剖位置可能会遇到各种病变；然而，关于它们的皮肤镜表现却知之甚少。本研究的目的是全面总结脐部病变皮肤镜特征的现有证据。
本研究纳入了评估脐部病变皮肤镜图像的研究。未设置年龄、种族或皮肤光型限制。排除评估脐部区域以外病变、缺乏皮肤镜图像和/或皮肤镜描述以及与主题无关的论文。检索了截至2023年5月底的Embase、Medline和Cochrane图书馆。使用乔安娜·布里格斯研究所的批判性评估工具来评估所选研究的偏倚风险。根据2011年牛津证据水平评估纳入研究的质量和证据水平。34项共报告39个病变的研究符合纳入标准并纳入定性分析。
黑色素瘤、痣、基底细胞癌、Pinkus纤维上皮瘤、玛丽·约瑟夫修女结节、蕈样肉芽肿、皮肤纤维瘤、子宫内膜异位症、表皮囊肿、肉芽肿、血管内乳头状内皮增生、扁平苔藓、脐石、脂溢性角化病和汗管瘤。
皮肤镜检查是一种非侵入性技术，可能有助于脐部病变的鉴别诊断。本研究的主要局限性在于研究中缺乏高水平证据，以及纳入研究之间应用的皮肤镜术语缺乏一致性。
