An Approach to Excision of Congenital Giant Pigmented Nevi in Infancy and Early Childhood

This paper presents a timely coordinated approach to complete excision of congenital giant pigmented nevi in infancy and early childhood based on a review of 78 patients with giant pigmented nevi of the head and neck, trunk, and/or extremity. Giant pigmented nevi in those selected for review measured from a minimum of 2 percent up to 45 percent total body surface (TBS). Giant nevi of the scalp were treated most effectively using tissue expansion, beginning as early as 3 months of age. Expanded forehead and neck flaps in combination with expanded full-thickness skin grafts were used in early excision of giant pigmented nevi of the face. Giant nevi of the trunk were treated using a combination of abdominoplasty technique, tissue expansion, and split-thickness skin graft, with early “large segment” excision and grafting being the most effective treatment of giant nevi covering the posterior trunk. Giant nevi of the extremities were treated most effectively with excision and graft. Expanded full-thickness skin grafts gave excellent coverage on the hands and feet.
