    Abstract
  •   Objective  To explore the dermatoscogic manifestations of basal cell carcinoma of the skin and analyze its diagnostic value, in order to understand the accuracy of dermatoscope in the diagnosis of basal cell carcinoma.  Methods  A total of 62 patients with suspected basal cell carcinoma were selected from the Dermatology Clinic of Fuyang People ' s Hospital from July 1, 2017 to December 31, 2019, including 29 males and 33 females, with an onset age of (70.34±4.41) years. The skin lesions of outpatients were observed by digital camera and dermatoscope, and pathological biopsy was performed. The results of pathological examination were taken as the gold standard, the accuracy of dermatoscope in the diagnosis of basal cell carcinoma was evaluated, and the consistency of dermatoscope and histopathological classification was analyzed.  Results  Among the 62 patients with suspected basal cell carcinoma, 47 were diagnosed as basal cell carcinoma by dermatoscope and pathology. The diagnostic sensitivity of dermatoscope was 95.92%, the specificity was 92.31%, the total coincidence rate was 95.16%, the misdiagnosis rate was 7.69%, the missed diagnosis rate was 4.08%, the Youden index was 0.882, the Kappa value was 0.858, and the consistency with pathological diagnosis was high (P=0.999). Among the dermatoscopic related indexes of basal cell carcinoma, there were significant differences in the positive rates of dermatoscogic features such as ulcer, multiple superficial erosion, bright red and white unstructured area, blue-gray oval nest, leafy structure and so on (all P < 0.05).  Conclusion  The diagnosis of basal cell carcinoma by dermatoscope is highly consistent with the results of pathological examination, and it has the characteristics of non-invasive, convenient and high accuracy, which is worthy of clinical promotion.
