Feature | Significance |
|---|---|
Asymmetry | Examined in both axes, using the dermatoscope. Colour and structures are assessed. Significant asymmetry of colour or structures within the lesion are recorded as a score of 1. |
Atypical pigment network | Many naevi have a uniform reticular pattern to the pigment distribution resembling chicken wire or a honeycomb structure with regular brown or black lines. An atypical network is recorded as a score of 1 if the network is irregular in thickness, irregular holes, or irregular colours. |
Blue structures or blue-white veil | The presence of any blue structure observed including a blue-white veil scores 1. |
