Predictors of malignancy in melanocytic lesions presenting as new lesions compared to baseline total body photography: A case-control study.

Melanomas presenting as new lesions are frequently featureless or feature poor on dermoscopy and difficult-to-diagnose on histopathology. In high-risk patients, the presence on any of the dermoscopic predictors of malignancy identified should prompt excision; however, the remaining lesions should be closely monitored.
