Its features include Asymmetry, boring of B prepare, Color variation, and large Diameter. These ABCD rules can be helpful, but many melanomas are not determine using them. For instance, the D of ABCD includes a lesion diameter greater than 6 mm in diameter. choose to an educated physician and global public, melanomas in Australia are diagnosed petty than 6 mm 60 percent of the time. Thus size alone is not a useful predictor, un little the lesion is large. Similarly, edge and food colouring variation are general in very comminuted new-made nevi that are not dysplastic. As nevi evolve beyond 2 to 4 mm, the variation becomes less and less in the normal nevus.

Conversely, the irregularity of edge and contort can be accentuated in the dysplastic nevus evolving into a melanoma. Thus, while the ABCD rule is useful as a carriage of thinking about morphology, exact adherence to it may return in the wanting(p) of some melanomas.
