[The ABCD rule in dermatoscopy: analysis of 500 melanocytic lesions].
500 melanocytic lesions were examined by dermatoscopy using the ABCD rule prior to excision and histologic diagnosis. Regular nevi (n = 272) exhibited a score of 3.55 +/- 0.87, nevi with histologic signs of dysplasia (n = 190) a score of 4.0 +/- 0.68 and melanomas (n = 30) a score of 5.08 +/- 1.24. This study suggests that the ABCD rule of dermatoscopy greatly facilitates the evaluation of melanocytic lesions. When the dermatoscopic score is higher than 4.2, melanoma should be considered.
