皮肤镜在色素型基底细胞癌中的临床诊断价值及有效性探讨

The clinical diagnostic value and effectiveness of dermoscopy in pigmented basal cell carcinoma

目的探讨皮肤镜在色素型基底细胞癌(pigmented basal cell carcinoma,PBCC)中的临床诊断价值及有效性。方法选取2017-03至2020-03我院诊治的疑似头面部色素型基底细胞癌患者93例,所有患者均经高频超声及皮肤镜诊断。参照病理学诊断结果比较两种诊断方法的准确率、灵敏度、特异度、误诊率、漏诊率及与病理诊断的一致性。结果高频超声和皮肤镜诊断PBCC的准确率、灵敏度、特异度、误诊率、漏诊率、Youden指数、Kappa值分别是83.87%、84.61%、82.14%、17.86%、15.38%、0.668、0.498和95.70%、96.92%、89.29%、10.71%、3.08%、0.862、0.654。结论在PBCC诊断中,皮肤镜比高频超声具有更高的诊断准确率、特异度和灵敏度,诊断结果与病理诊断一致性好。

Objective To analyze the clinical diagnosis value and effectiveness of dermoscopy in pigmented basal cell carcinoma(PBCC).Methods A total of 93 patients with suspected pigmented basal cell carcinoma admitted to our hospital from March 2017 to March 2020 were selected.All patients were diagnosed by high-frequency ultrasound and dermoscopy.The accuracy,sensitivity,specificity misdiagnosis rate,missed diagnosis rate and consistency of the two diagnostic methods were compared with the pathological diagnosis results.Results The accuracy,sensitivity,specificity,misdiagnosis rate,missed diagnosis rate,Youden index,and Kappa value of high-frequency ultrasound and dermoscopy in the diagnosis of PBCC are83.87%,84.61%,82.14%,17.86%,15.38%,0.668,0.498和95.70%,96.92%,89.29%,10.71%,3.08%,0.862,0.654.Conclusions In the diagnosis of PBCC,dermoscopy has higher diagnostic accuracy,specificity and sensitivity than high-frequency ultrasound,and the diagnosis results are consistent with pathological diagnosis.
