How should we define 'chaos'? Any feature that makes you suspicious
Lesions which pique interest because of their asymmetry deserve closer scrunity
A dermatoscopist performing a skin check recognises benign lesions in the same way that we recognise people’s faces — by pattern recognition.
Lesions that are expected — primarily seborrhoeic keratoses/solar lentigines, naevi, haemangiomas, dermatofibromas and sebaceous gland hyperplasia — are “recognised” because of their distinctive morphology.
These lesions are expected to have reasonable biologic symmetry, just as faces have symmetry. If there is a lack of symmetry, known
