Two-stage surgical treatment of giant congenital melanocytic nevus around the auricle.

Background: This study presents the results of complete excision of giant congenital melanocytic nevi (GCMN) on the auricle, forehead, or periorbital area combined with tissue expansion, and skin graft transplantation performed in two stages based on 10 years of experience.

Aims: To solve the giant congenital melanocytic nevi on the auricle, forehead, or periorbital area with two-stage operation.

Patients/methods: A total of 21 patients with GCMN were included in this study. The operation combined tissue expander and skin graft transplantation.

Result: All GCMNs were successfully and completely excised. No patient in the study group had experienced skin contraction or auricular deformation at 3 years after treatment.

Conclusion: Two-stage operation is effective for removing GCMN on the auricle or face and can achieve good oncological and cosmetic results.
