Nevi Malignant Melanoma
We recommend either short - term mole monitoring or a biopsy for these lesions, depending on the clinician’s level of experience.

Global Evaluation of Lesion
Color: Generally more than 3 colors
Brown Blue White Gray Black Red
Asymmetry: Refers to the non-
uniform distribution of colors and structures on either side of the axis and not by lesion shape.
Disorganization: Non-uniformity of
structures and their departure from the expected locations traditionally seen in benign lesions.
Malignant Patterns
Malignant Patterns
A pattern is created by the placement of structures in a lesion. When these structures are asymmetrically distributed and there are more than 3 colors noted, they create patterns seen in many malignant lesions.
