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

2. Benign Patterns
A pattern is created by the placement of structures
in a lesion. When these structures are symmetrically
distributed and there are less than 3 colors (light
brown, dark brown, and black) noted, they create a
pattern seen in many benign lesions.
The most common benign patterns are:
Reticular Globular Homogeneous
