Congenital melanocytic nevi (CMN) are a quite common congenital disorder. Over years, surgical excision was proposed to the patients because transformation into a malignant skin tumor (melanoma) was feared. Recent data proof that the risk for malignancy was overestimated. Nowadays still a lot of patients express their wish for surgical removal out of aesthetic reasons and psychological impacts. Many patients and families experience stigmatization because of the nevus. To proof a medical indication for surgical removal the investigators want to evaluate the quality of life and stigmatization before and after nevus surgery.
