Abstract
ABCD Rule of Dermoscopy
Definition
The ABCD rule of dermoscopy (Table 1) was the first method of the so-called melanoma algorithms in dermoscopy. With a scoring system (total dermoscopy score, TDS), a grading of pigmented lesions is possible with respect to their malignant potential. The TDS is used to classify the lesion as benign (TDS < 4.75), suspicious (TDS < 4.75−5.45), or malignant (TDS > 5.45).
ABC Point List of Dermoscopy
Definition
The ABC point list of dermoscopy (Table 2) is a pointlist algorithm to discriminate benign melanocytic lesions from cutaneous melanoma. It is based on statistical analysis. A lesion should be considered a malignant lesion if the score is four points or higher.
