The Internet has become an increasingly used tool for patient education and the coordination of support groups. For families with children diagnosed with congenital melanocytic nevus, this is also the case. To evaluate the quality of congenital melanocytic nevus-related information on the Internet, a standardized assessment of web sites was used. The overall Internet informational and support resources regarding congenital melanocytic nevus were found to be accurate and user friendly but limited. The authors recommend practitioners direct patient families to www.nevusnetwork.org as a starting point, and supplement an interest in pictures and information regarding support groups with visits to www.dermatlas.org and http://groups.MSN.com/AussieNevusSupportGroup.
