Be mindful of melanoma mimics
The presentation of melanoma can break the clinical pattern of other lesions at the same anatomical location by virtue of its size, shape or colour.

They will frequently clinically resemble a naevus, solar lentigo, lichen planus-like keratosis or seborrhoeic keratoses.
