Manner of death determination in a case of gastric mucosal tears

Gastric tears are rarely described in the forensic pathological literature, although they can lead to a fatal acute exsanguination. Such lesions can arise from several conditions leading to an increased intragastric pressure, such as Mallory Weiss syndrome, cardiopulmonary resuscitation, acute barotrauma and operative procedures, showing peculiar morphological features. We present a case of a 32-year-old drug addicted white woman found dead in a pool of blood in the house of her drug dealer, after taking a dose of intravenous heroin. At autopsy, abundant bloody gastric content and multiple and long gastric tears, extending from the cardias and fundus regions to the gastric corpus were observed; one of them involved the subserous region, resulting in a gastric wall rupture. The victim had no history of recent vomiting and of gastro-intestinal pathologies. Drugs and ethanol levels detected in the specimens of the victim were not consistent with lethal concentrations, thus the death was attributed to acute exsanguination. After reviewing the literature, it turned out that morphological aspects of the gastric tears, such as number, size and topographical distribution, observed at autopsy were atypical compared to those of typical gastric lacerations.
