Which technique for removing nevi is least scarring?

Abstract

A shave biopsy with a razor blade or #15 scalpel is the best approach for a facial nevus, assuming malignancy is not suspected. The resulting scar is usually flat, smaller than the lesion, has no suture lines, and -- if shaved in mid or upper dermis -- has a low risk of producing a hypertrophic or hypotrophic scar (strength of recommendation: C, expert opinion, committee guidelines).
