目的探讨皮肤镜图像分析技术对于基底细胞癌(basal cell carcinoma,BCC)的诊断及临床应用价值。方法收集头面部可疑BCC的皮损127例,在临床肉眼诊断的基础上,根据皮肤镜指征进行诊断,后经组织病理确诊,将诊断结果进行对照分析和统计学处理。结果将皮肤镜诊断结果经组织病理确诊BCC122例,经分析显示出皮肤镜诊断的灵敏度89.34%,特异度95.90%,诊断符合率达96.06%,比肉眼诊断正确率提高了32.28%。本文证实BCC的临床各型和皮肤镜所有诊断指征,除BCC纤维上皮瘤型外,其它各型在头面部均有显示。结论皮肤镜在头面部BCC的诊断中显示出较好的灵敏度和特异度,在临床对减少盲目活检或手术切除范围及选择恰当的治疗方法有意义,对头面部皮损的康复与美容起到积极的推动作用。
Objective To investigate the diagnostic and clinical value of dermoscopic image analysis for basal cell carcinoma (BCC). Methods The lesions of the head and face suspected BCC were collected in 127 cases. On the basis of clinical diagnosis, dermoscopy indications were used to diagnose the lesions. After histopathological diagnosis, the diagnostic results were analyzed and statistically analyzed. Results The diagnostic results of dermoscopy were confirmed by histopathology. The results showed that the sensitivity and specificity of dermatoscopy were 89.34% and 95.90%, respectively. The diagnostic coincidence rate was 96.06%, which was 32.28% higher than that of the naked eye. This article confirmed that all clinical signs of BCC and dermoscopy diagnostic indications, in addition to BCC fibroepithelioma, the other types of head and face are shown. Conclusions Dermatoscopy shows good sensitivity and specificity in the diagnosis of BCC in the head and face. It is meaningful in clinic to reduce the range of blind biopsy or surgical resection and select appropriate treatment methods, and plays a positive role in the rehabilitation and beauty of head and face lesions The role of promotion.
