Chen et al1 conclude on the basis of a meta-analysis of all published studies that there are no firm data to support the commonly held assumption that dermatologists can identify lesions that may be melanoma more accurately than primary care physicians. The ability of both groups to correctly identify potentially dangerous lesions that warrant biopsy or referral for biopsy was in both cases very high—up to 100%.
