An unusual cause of caustic burns.

Two children in far northern Western Australia tattooed their arms with maangga berries (Grevillea pyramidalis ssp. leucadendron), which resulted in unintentional, caustic, partial thickness skin burns requiring specialist burn care. An understanding of the chemistry of the burn agent (5-n-alkyl resorcinol), appropriate first aid management and referral, and possible physiological sequelae are essential for optimal medical management and preventive community education.
