Two cases of lightning strikes resulting in Lichtenberg figures

open access: yesDermatologica Sinica, 2014
Lightning strikes may cause serious injury such as burns and cardiac rhythm disorders or death through the powerful electric current. Lichtenberg figures, also known as the “picture of the lightning” are the important clues for lightning strikes.
