Giant congenital melanocytic nevi (GCMN) occur in 1:20,000 livebirths and are associated with increased risk of malignant transformation. The treatment of GCMN from 1981 to 2010 in a tertiary referral center was reviewed evaluating the modalities used, cosmetic results, associated complications, and malignant transformation. Of 35 patients, 25 underwent surgery. Curettage was most frequently used (64%) followed by excision and tissue expansion (20%). Six percent of the patients treated with curettage, and 78% of the patients who received excision surgery required more than 1 planned procedure, and 25% versus 44% required unplanned additional surgery, respectively. Complications were noted in 25% and 67% of the patients, respectively. Cosmetic result was satisfying in 76% of patients without difference between the groups. No malignant transformation was found during a mean follow-up of 11 years. Curettage is a gentle alternative to excision with a lower complication rate and good cosmetic outcome.
