Clinical, Dermoscopic and Histopathologic Correlation in Melanocytic Nevi

Dermoscopy is a noninvasive technique that facilitates the diagnosis of melanocytic nevus (MN). Different algorithms are used in the differential diagnosis of melanocytic lesions. In this study, we aimed to correlate the sensitivity and specificity of the ABCD rule, 7 point control list and pattern analysis in MN. A total of 60 MNs of 38 patients who applied to dermatology outpatient clinic have been evaluated. Hand dermatoscopy (Dermatoscope Delta 10) and digital dermatoscope (MoleMax II) were used for dermoscopic examination, and each of the dermoscopic images were assessed with the pattern analysis, the 7 point checklist and the ABCD rule. After dermoscopic examination, lesions were examined histopathologically following excisional or punch biopsy. The concordance between dermoscopic and histopathologic diagnosis were evaluated. In our study, the sensitivities of ABCD rule, 7 point control list and pattern analysis were 94.6%, 92.9% and 97.5% respectively. The specificities were 78.3%, 85% and 95% respectively. According to our study, pattern analysis method had the highest specificity and sensitivity
