The Three Point Technique
The three point technique was developed by Soyer et al who recognised that dermoscopy could be a screening tool for all those involved in skin care. As a result it is a simplified technique to screen suspicious lesions and it particularly useful for the novice. Through the dermatoscope, it assesses individual lesions on three criteria:
Asymmetry of colour and dermatoscopic structures
Presence of an atypical network
Presence of blue-white structures or veil
Each criterion, if present scores 1 point. Any lesions scoring two or above should be considered for biopsy and warrant possible excision. A summary of the technique can be found in table table1.1. A preliminary study of 231 pigmented skin lesions showed that after one hours training six inexperienced dermatologists were able to improve their sensitivity in recognising skin cancer from 69.7% to 96.3% . In a later study with 150 participants, Soyer demonstrated 91% sensitivity, with those in the cohort declaring no experience in dermoscopy still achieving 87% sensitivity for melanoma. Further studies are required to confirm this finding.
