Abstract BACKGROUND: The parallel ridge pattern (PRP) is considered as the dermoscopic hallmark of acral melanoma (AM). However, it was recently shown that approximately one third of AM do not display dermoscopically a PRP, rendering their detection more troublesome. OBJECTIVE: To investigate the diagnostic accuracy of dermoscopic criteria for the diagnosis of AM. METHODS: Dermoscopic images of consecutive cases of histopathologically diagnosed AMs and acral nevi with histopathologic diagnosis or with at least 1 year of follow up were evaluated by 3 independent investigators for the presence of pre-defined criteria. Crude odds ratios, adjusted odds ratios and corresponding 95% confidence intervals were calculated by univariate and multivariate logistic regression, respectively. ROC curves were used to choose among competing classification schemes. RESULTS: A total of 603 lesions (472 nevi and 131 AMs) were included in the study. A scoring system (named BRAAFF) composed of 6 variables was associated with optimal area under curve and sensitivity for the diagnosis of AM. This method included 4 positive (blotches irregular, ridge pattern, asymmetry of structures and asymmetry of colours) and 2 negative predictors (furrow pattern and fibrillar pattern). CONCLUSION: The BRAAFF checklist significantly improves the diagnostic accuracy of dermoscopy for the diagnosis of AM. This article is protected by copyright. All rights reserved. |
