The danger of grey circles
Malignant lesions often ‘break the pattern’ clinically, which is consistent with the chaotic behaviour of malignant tissue.
This can be expressed by a lesion standing out because of its colour, size or shape. If a new lesion at mature age resembles a work of art, but it is not a tattoo, this should raise suspicion.
Melanomas can sometimes grow slowly and appear not to be changing, but the onset at mature age is the important clue, and examination with a dermatoscope can then be used to unmask important objective clues to malignancy.
