The Eraser Challenge Among School-age Children.

Skin-related, self-destructive behaviors are being increasingly reported among school-age children. Often disguised as innocuous "challenges," these disturbing actions may have the potential for serious and permanent sequelae. Interest and subsequent participation in these behaviors may also be spread "virally," facilitated by social networking sites that allow participants-regardless of age-to share photographs or videos of the activities in question. Consequently, parents and health care providers must learn to recognize signs and symptoms of these disturbing behaviors and make concerted efforts to protect this uniquely vulnerable population of pediatric patients.
