title: Surgical treatment of large cutaneous lesions of the back in children by concentric cutaneous mobilization.
abstract: Excision of large cutaneous lesions of the back, such as giant nevi in children, represents a major surgical challenge. Actually, many authors use tissue expanders. Recently, we have proposed, through a better evaluation of the biomechanical properties of the skin, a natural expansion mode using the postoperative tension. This expansion is natural and delayed. In the back the natural expansion can be created by concentric excision, which takes maximum advantage of the possibilities of cutaneous mobilization of the back. The concentric excision has been used in 12 children presenting with cutaneous lesions of the back involving more than 30 percent of the dorsal anatomic unit. Nine patients underwent total excision; two patients were treated in one stage, four patients in two stages, and three patients in three stages. Three patients could not have total excision. The follow-up was uneventful, except in one patient who presented with wound dehiscence. The follow-up was 1 to 2 years and showed a modest scar widening (< 4 mm) in three patients, moderate widening (> 4 min, < 7 mm) in three patients, and significant widening (> 10 mm) in three patients. The systematization of the cutaneous mobilization for each region of the back has allowed us to optimize the utilization of peripheral normal tissue in the surgical treatment of large cutaneous lesions of the back. In some circumstances, the gain in tissue has been superior to that we usually obtain with skin expanders and with lesser cost, lesser pain, and fewer risks.
