“…It is uncertain whether the published series included a significant proportion of pigmented BCC. 21 There are some limitations to our study. Despite the small sample size, all patients were treated by a single Mohs surgeon, thus limiting the interoperator variability.…”

There is a need for adjuvant imaging techniques that would allow reducing the number of slow Mohs stages. This study aimed to evaluate the use of dermoscopy in the demarcation of basal cell carcinoma (BCC) surgical margins for slow Mohs surgery. This was a retrospective study over 3 years (2016-2019), including patients with BCC excised using slow Mohs surgery. On the basis of the treatment received, the patients were divided into 2 groups: group 1 (28 BCC) and group 2 (26 BCC). In group 2, BCC margins were demarcated using dermoscopy. A total of 54 patients were enrolled in the study. The number of positive lateral margins was significantly lower in the group where BCC margins were demarcated using dermoscopy (19% vs 53%, P = .012). In this group, the number of Mohs stages needed to achieve complete clearance was significantly lower. However, the mean interval between the first Mohs excision and Mohs clearance was not significantly different between the 2 groups (9 ± 4 vs 12 ± 7 days). In conclusion, preoperative dermoscopy is useful for reducing the number of positive lateral margins and the number of slow Mohs stages in treating BCC especially pigmented tumors.

“…Foreign research on dermoscopy in surgery mainly focused on determinating the margin of BCC [43] and SCC, [44] and the combined application of Mohs micrographic surgery. [45] The comparison between using a naked eye and a dermoscope showed that using dermoscopic detection of the surgical excision margin of BCC is superior to observation with the naked eye. [46] For traditional surgery, dermoscopy can more accurately trace the tumor boundary before surgery, so that the tumor tissue can be excised as cleanly as possible to avoid recurrences and secondary surgery.…”

Objective:Dermoscopy is a useful technique for improving the diagnostic accuracy of various types of skin disorders. In China, dermoscopy has been widely accepted, and domestic researchers have made tremendous progress in the field of dermoscopy. The main purpose of this review is to summarize the current status of dermoscopy in China and identify its future directions.Data sources:Articles included in this review were obtained by searching the following databases: Wanfang, China National Knowledge Infrastructure, PubMed, and the Web of Science. We focused on research published before 2019 with keywords including dermoscopy, dermoscopic, dermoscope and trichoscopy.Study selection:A total of 50 studies were selected. Of these studies, 20 studies were in Chinese and 30 in English, research samples of all the studies were collected from Chinese populations.Results:Since 2000, more than 380 articles about dermoscopy have been published in domestic or foreign journals. Dermoscopy can improve the diagnostic accuracy of neoplastic diseases, evaluating the therapeutic effect of treatment, and determining the treatment endpoint, and it can also assist in the differential diagnosis of inflammatory diseases and in the assessment of the severity of the disease. In addition, researches about the applications of dermoscopy during surgical treatment have been published. Training courses aiming to improve the diagnostic ability of dermatologists, either face-to-face or online, have been offered. The Chinese Skin Image Database, launched in 2017 as a work platform for dermatologists, has promoted the development of dermoscopy in China. Computer-aided diagnostic systems based on the Chinese population are ready for use. In the future, cooperation, resource sharing, talent development, image management, and computer-aided diagnosis will be important directions for the development of dermoscopy in China.Conclusion:Dermoscopy has been widely used and developed in China, however, it still needs to address more challenges in the future.

“…Dermoscopy ('non-mapped') has been used as an adjunctive method in MMS to demarcate preoperative margins and reduce the number of stages; however, its results are conflicting. [8][9][10][11][12] One factor that may influence these results is that some studies included well-defined tumours, for which dermoscopy is 'less needed' for tumour demarcation. Furthermore, such studies probably included Mohs surgeons who were already trained and interested in dermoscopy, which increased the difficulty of evaluating the extent to which dermoscopy was helpful.…”
