Epidermal naevi are hamartomas that are characterized by hyperplasia of the epidermis and adnexal structures and may be associated with serious disfiguration. Management of epidermal naevi is challenging. We present here our experience with cryosurgery in the treatment of verrucous epidermal naevi. The aim of this study was to determine the efficacy and safety of cryosurgery for the treatment of epidermal naevi. Nine patients with verrucous epidermal naevi and two with extensive unilateral epidermal naevus were treated with cryosurgery. Two cycles of open spray technique were used, 10-15 sec each, depending on the size and extent of the naevus. Ten patients had their naevi treated successfully in 2-5 sessions with two cycles of therapy, and the cosmetic result was excellent with no scarring. One patient showed a relapse within 8 months after the treatment. One patient with phototype IV developed hypochromic scarring, but repigmentation occurred after 6 months. Postoperative healing time was 10-20 days. Cryosurgery is an extremely effective therapeutic modality for the treatment of epidermal naevi. The low cost, the simplicity of the technique and the good cosmetic result makes cryosurgery an excellent therapeutic modality for the treatment of epidermal naevus.
表皮痣是一种错构瘤，其特征为表皮和附属器结构增生，可能伴有严重的毁容。表皮痣的治疗具有挑战性。我们在此介绍我们使用冷冻手术治疗疣状表皮痣的经验。本研究的目的是确定冷冻手术治疗表皮痣的疗效和安全性。9例疣状表皮痣患者和2例广泛性单侧表皮痣患者接受了冷冻手术治疗。根据痣的大小和范围，采用开放喷雾技术进行两个周期的治疗，每个周期10 - 15秒。10例患者通过两个周期的治疗，在2 - 5次治疗后痣成功治愈，美容效果极佳，无瘢痕形成。1例患者在治疗后8个月内复发。1例IV型皮肤患者出现色素减退性瘢痕，但6个月后色素重新沉着。术后愈合时间为10 - 20天。冷冻手术是治疗表皮痣的一种极其有效的治疗方式。其低成本、技术简单以及良好的美容效果使冷冻手术成为治疗表皮痣的一种极佳治疗方式。
