• To investigate the diagnostic value of dermoscopy in defining the tumor margin of basal cell carcinoma (BCC) for the appropriate surgical margin. A total of 107 BCC patients were enrolled for this study. The tumor boundaries were observed by naked eye and dermoscope respectively, and 5 mm outward was used as surgical margin according to the dermoscopy‐defined margin. Pathological examinations were performed at 2 mm intervals in the direction previously marked and the effect was assessed accordingly. There were still 16.8% of patients whose visual margin was insufficient to the dermoscopy‐detected margin. With 2 mm excision margin from the dermoscopy‐guided tumor margin, excision range in 12 patients (11.2%) proved to be inadequate, but only 18 surgical margins (4.2%) in the whole 428 excision margin specimens proved to be tumor‐positive. While with 4 mm margin, residual lesion was observed in 2 (0.5%) of 107 BCC patients, and positive margin was found in 2 (0.3%) of 428 margin specimen. There has been no recurrence in our study so far. Dermoscopy is superior to visual inspection for defining BCC tumor margin. Under preoperative dermoscopy detection, a 4 mm excision margin of BCC can achieve a radical resection rate of 98.1%, and 92.3% for a 2 mm excision margin of pigmented BCC.
