Electrocution stigmas in organ damage: The pathological marks

Abstract

Background: Diagnostic criteria for electrocution related death are still a challenge in forensic pathology and it seems that the electrical mark is the only reliable evidence. Methods: A comparison of histological and morphological findings of skin and internal organs from an autopsy series of electrocution deaths with those mostly reported in literature as representative for electrocution. Results: The morphological changes of heart, brain and other main internal organs are still unspecific. Organ’s damage observed in electrocution deaths shows a wide variability, not reliable for a certain diagnosis of electrocution. The electrical mark is still the golden standard for diagnosis of electrocution. Conclusions: In electrocution related deaths, pathological findings of the main internal organs are not enough evidence to support with certainty a post-mortem diagnosis that a victim suffered an electrical damage. Although the organ histological changes are undoubtedly the starting point for a better understanding of the fatal even, the diagnosis of death from electrical damage is still a dark and unsolved chapter. The electrical mark still represents a fundamental indicator above all in the medical-legal field, but the identification of pathognomonic elements and signs not limited to the skin alone could be a valid help in the future, especially in unclear cases.
