Type 1 (very high risk) |

|
|
|
|
Type 2 (high risk) |
Lesion with a pigment network and subtle new ELM features that may suggest melanoma but often are also seen in atypical nevi. |
|
|
|
|
Type 3 (medium risk) |
Lesion with a pigment network carrying subtle perturbations that can be detected in atypical naevus as well as in melanocytic hyperplasia. |
|
|
|
|
Type 4 (low risk) |
Lesion with a benign appearing network. |
