Abstract

Background: This study analyzes the outcomes of 15 children who underwent inner foreskin free grafting for penile divided nevus to propose a grading system for evaluating post-operative appearance and share key surgical techniques and experiences.

Methods: Clinical data were collected from children diagnosed with penile divided nevus between July 2023 and January 2025. The appearance was graded based on the color match between the penis and the transplanted skin, as well as whether the grafted skin was flat.

Results: A total of 15 children with penile divided nevus were enrolled, with an average age of 9.6 ± 3.0 years (ranging from 3 to 16 years). The size of the nevus on the penis ranged from 1 × 0.5 cm to 3 × 2 cm, and the nevus on the inner foreskin ranged from 1 × 0.5 cm to 3 × 2 cm. Pathological analysis confirmed junctional nevi in 3 children and compound nevi in 12 children. All grafts showed good viability with postoperative follow-ups 5.8 ± 3.0 months. Ten cases were classified as grade I in terms of appearance, 1 case as grade II, 3 cases as grade III, and 1 case as grade IV. In one case, newly developed pigmented nevi were observed around the grafted area and in the coronal sulcus at 1 month postoperatively.

Conclusion: The free skin grafting technique using inner foreskin for the treatment of penile divided nevus has a high skin graft survival rate. Preoperative separation of preputial adhesions and performing the surgery after complete keratinization of the glans and inner foreskin are essential.

游离内包皮移植治疗儿童阴茎分裂痣的预后及手术经验。

背景：本研究对15例儿童阴茎分裂痣行游离内包皮植入术的结果进行分析，提出一种评价术后外观的评分体系，并分享手术关键技术和经验。方法：收集2023年7月~ 2025年1月诊断为阴茎分裂痣患儿的临床资料。根据阴茎与移植皮肤的颜色匹配以及移植皮肤是否平整，对外观进行分级。结果：共纳入15例阴茎分裂痣患儿，平均年龄9.6±3.0岁（3 ~ 16岁）。阴茎上痣大小为1 × 0.5 cm ~ 3 × 2 cm，内包皮上痣大小为1 × 0.5 cm ~ 3 × 2 cm。病理分析证实交界性痣3例，复合性痣12例。术后随访5.8±3.0个月，移植物存活良好。外观I级10例，II级1例，III级3例，IV级1例。术后1个月，1例移植区周围及冠状沟内出现新发色素痣。结论：采用内包皮游离植皮技术治疗阴茎分裂痣，植皮成活率高。术前分离包皮粘连，并在龟头和内包皮完全角化后进行手术是必不可少的。
