The indication for surgical treatment of congenital nevocellular nevi results from aesthetic-cosmetic consideration as well as from the increased risk of melanomatous transformation. No postoperative development of malignant melanoma arising from the congenital nevus was seen in any of the patients during the time of follow-up. No serious long-term complications were seen. In case of large and giant nevi, permanent removal of pigmentation was better than in small or medium-sized nevi. Dermabrasion proved to be an adequate modality for removal of pigmentation in the therapy of large and giant congenital nevocellular nevi when assessed within 2 years following the procedure.
Early treatment is crucial for permanent removal of pigmentation.
Long-term effects remain to be adequately monitored.
