Congenital Giant Nevocellular Nevus of the Back with Deep Extension to the Fat and Fascia

Abstract

The presence of deep pigmentation in a giant congenital nevus makes its complete removal very difficult and should be taken into consideration when planning for treatment. A clinical case in which the pigmented lesion was found to extend deep into the muscle fascia is described. The lesion was surgically removed with an acceptable functional and aesthetic result through the utilization of tissue expansion. The development of new surgical techniques and the expansion of laser technology will possibly provide new treatment options in the future. Emphasis should be placed on aesthetics and function, because the excision based only on oncological anticipation is no longer valid. The presence of deep pigmentation makes certain treatment options less effective than surgical ablation.
