Lichtenberg figures—morphological findings

Following a witnessed lethal lightning strike of an adult male who was standing outside in a storm, numerous Lichtenberg figures were identified upon external examination of the body. Sectioning across multiple areas of linear erythema in the figures showed no subcutaneous hemorrhage. This was later...

description Following a witnessed lethal lightning strike of an adult male who was standing outside in a storm, numerous Lichtenberg figures were identified upon external examination of the body. Sectioning across multiple areas of linear erythema in the figures showed no subcutaneous hemorrhage. This was later confirmed on histology which showed only subtle dermal capillary dilatation with no interstitial hemorrhage or inflammation in these areas. The only areas of interstitial hemorrhage were present in adjacent scattered punctate burns from arcing. The documented resolution of Lichtenberg figures within hours would be more in keeping with temporary functional capillary dilatation, shown in this case, rather than with tissue alteration by interstitial hemorrhage or inflammation.
