Skin-Fat Composite Grafts after Excisions of Medium Sized Congenital Melanocytic Nevi in Children

Congenital melanocytic nevi (CMN) are defined as melanocytic nevi that present at birth or within the first few months of life. Small or medium-sized nevi occur in approximately 1% to 6% of all newborns, whereas giant nevi occur in approximately 1 in 20,000 [1-3]. There are two main considerations in the treatment of CMN. The first is predicting the risk of its transformation to melanoma, and the second is aesthetic satisfaction. Generally, it is known that the bigger the nevus, the greater the risk of malignant transformation. The risk of melanoma transformation of small and mediumsized CMN is controversial, but it is generally thought to be less than 4.9% [4]. Currently, there is no consensus regarding the management of small and medium-sized CMN, whereas interventions are highly recommended early in life for giant congenital nevi. Nevertheless, even a small nevus on the face or other visible area may precipitate the need for surgery for cosmetic and psychological reasons. Some surgeons believe that surgical management should be considered early, so that excision of the nevus and scar maturaDae Hwa Kim, Il Hwan Byun, Dae Hyun Lew, Won Jai Lee
