Global Evaluation of Lesion

Color: Generally, 3 or fewer

Light brown Dark brown Black

Symmetry: Refers to the distribution of colors and structures on either side of the axis and not solely by contour.

Organization: Uniformity of structures and their distribution in specific locations within the lesion

Benign Patterns

The most common benign patterns are:

And six dermoscopy images all showing a uniform network that thins at the periphery.
