The electrical burn mark was produced on 25 dead bodies. Alongside 25 cases of electrocution deaths were included for comparison. Slides were prepared and stained with hematoxylin-eosin stains. Intraepidermal and subepidermal separation; coagulative necrosis of the epidermis; nuclear elongation and hyperchromasia of epidermal cells; homogenization of the dermis; nuclear elongation and hyperchromasia of hair follicles, sweat glands, sebaceous glands, and blood vessel endothelium were studied for histopathological changes and graded. The findings of the study suggest that the histopathological changes in electrical burn marks are due to the physical effect of heat produced by the electric current. The classical histopathological features of electrical burn mark cannot differentiate between AME and PME burn marks. However, careful evaluation of grading of the dermal changes can be helpful in differentiating AME and PME burn marks. Highest grade of dermal thickness homogenization and highest grade of nuclear elongation of dermal appendages were significantly more in the antemortem electrical burn marks than PME burn marks.
