MELANOCYTIC LESIONS | ELM FEATURES |
---|---|
Type 1 (very high risk) | Lesion with a pigment network and any of the classical ELM features specific for melanoma (pseudopods, radial streaming, blue-gray veil, atypical vessel, etc.) |
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. |
Type 5 (very low risk) | Lesion with a benign appearing network and with a globular pattern or another benign ELM pattern. |
