Dermatologic Injury

The six main dermatologic manifestations of lighting injury are feathering burns (Lichtenberg figures), flash burns, punctate burns, contact burns, erythema, and blistering, and linear streaking. The pathognomonic skin finding for lightning is the Lichtenberg figure, which results from electron showering over the skin surface, which is not a true burn.13 Lichtenberg figures are superficial, appear in a fern pattern, and resolve within 24 h ( Fig 197-1). A comatose patient exhibiting Lichtenberg figures should be treated as a victim of lightning injury. Flash burns are similar to those found in welders, appear as mild erythema, and may involve the cornea. Punctate burns look similar to cigarette burns in that they are usually smaller than 1 cm and are full-thickness burns. Contact burns occur when metal worn close to the skin, such as coins, zippers, and belts, is heated by the lightning current. Erythema and blistering are usually transient, and superficial skin loss may occur. Linear burns may be seen in areas of sweat, such as the axilla or groin, and are full-thickness burns usually less than 5 cm wide. Less common burns found on lightning victims include those associated with ignition of clothing. Entrance and exit wounds, characteristic of nonlightning electrical injuries, are not commonly seen in lightning victims.
