OBJECTIVES: To examine whether histological examination of all tissue removed by general practitioners in minor surgery increases the rate of detection of clinically important skin lesions, and to assess the impact of such a policy on pathologists’ workload. DESIGN: Before and after comparison. SETTING: Stratified random sample of 257 general practitioner partnerships from the catchment areas of 19 English pathology laboratories.
