In this article, we present our experience of group lightning injury.Individual injuries are most common after single strikes. The largest group previously reported was 10 patients. In our series, 17 victims were hit by a single strike; 11 were admitted to the hospital and 6 were discharged from the accident and emergency department. Although injured under the same circumstances, these patients presented with a wide range of symptoms and signs. We also describe a characteristic burn pattern, the "tip-toe sign."
