THE APPLICATION OF THE 7-POINT CHECKLIST IN THE ASSESSMENT OF BENIGN PIGMENTED LESIONS

One hundred consecutive histologically benign lesions seen at a Pigmented lesion clinic were studied prospectively to assess the diagnostic accuracy of the seven-point check-list. Lesions were scored by both patient and physician. Thirty per cent of lesions attained a suspicious score. While there was a high level of agreement between patient and clinician regarding the individual characteristics of a lesion as defined in the check-list, final assessments differed. Most patients considered their lesions suspicious, whereas the clinicians correctly recognized that in 94% cases they were benign. The seven-point check-list often fails to exclude common benign pigmented lesions. The revised (1989) check-list is even less specific (70% of lesions achieving a suspicious score). Such check-lists are difficult for the inexperienced to interpret. Clinical familiarity is required in order to provide a confident diagnosis. Future emphasis should be directed towards improving screening in primary care.
