Patients frequently request removal of benign papular naevi for cosmetic or functional reasons. Shave excision plus electrocautery is probably the most widely used method of removal, but this method is said to result in retained hair or pigment if deeply pigmented or hairy naevi are treated. In a prospective study, 82 benign papular naevi of all types were treated by shave excision using hot-wire electrocautery for haemostasis. Details of the naevi were accurately recorded before treatment and reassessment of shave sites carried out at 6-8 months. At review, a scar was visible at only 63% (52/82) of shave sites and all of these were cosmetically acceptable. Only 27% (15/55) of the initially pigmented naevi retained pigment and only 24% (5/21) of the initially hairy naevi regrew hair. Shave excision and electrocautery of benign naevi, including hairy and deeply pigmented ones, produce excellent cosmetic results. The patient must be warned that there is a potential risk of a scar or pigment remaining after shave excision of any naevus and for hair regrowth after shave excision of hairy naevi.
患者常因美容或功能原因要求去除良性丘疹性痣。剃除术加电灼术可能是应用最广泛的去除方法，但据说如果治疗色素沉着深或多毛的痣，这种方法会导致毛发或色素残留。在一项前瞻性研究中，对82例各种类型的良性丘疹性痣采用热丝电灼止血的剃除术进行治疗。治疗前准确记录痣的详细情况，并在6 - 8个月时对剃除部位进行重新评估。复查时，仅63%（52/82）的剃除部位可见瘢痕，且所有这些瘢痕在美容上均可接受。最初有色素沉着的痣中只有27%（15/55）残留色素，最初多毛的痣中只有24%（5/21）重新长出毛发。对良性痣，包括多毛和色素沉着深的痣进行剃除术和电灼术，可产生极佳的美容效果。必须告知患者，任何痣剃除术后都有留下瘢痕或色素的潜在风险，多毛痣剃除术后有毛发再生的潜在风险。
