Sumario:Surgical excision of a giant congenital melanocytic nevus (GCMN) results in a full-thickness skin defect that is usually difficult to reconstruct even with tissue expansion or skin grafting. Here, we report the first case of GCMN treated with a combination of cultured epithelial autografts (CEAs) and mesh-skin grafts to reconstruct a large skin defect after surgical excision. A 14-month-old girl had a GCMN occupying 20% of the total body surface area of her neck and back. A 5-stage, full-thickness excision was performed between the age of 14 and 25 months. In each intervention, the wound after excision was covered with 1:6 mesh-skin grafts and CEAs, except for the neck, where patch skin grafts and CEAs were used. The skin grafts and CEAs were engrafted without shedding and epithelialization was completed within 3-4 weeks. Eighteen months after the last surgery, a mesh-like scar remained, with no recurrence or severe contracture observed. The cosmetic appearances of the donor sites (the scalp and lower abdomen) were acceptable. The application of CEAs with mesh-skin grafts has been established for the treatment of severe burns. This combined method also provides a possible option for the treatment of GCMNs.
