Abstract
Purpose
Cases of iron intoxication are not very often encountered in toxicology practice, and most of those reported concern accidental intoxications with iron supplements in young children. The paper presents a rare case of a suicide by intoxication in an adult woman who ingested a solution of iron (III) chloride.
Methods
A forensic was at the Department of Forensic Medicine, PMU in Szczecin. Toxicology tests of blood sampled from the deceased were performed using a 644 CIBA CORNING ion selective analyzer and proprietary reagent kits. Histopathological was with the use of the standard staining protocol (hematoxylin and eosin) and staining specific for iron (Prussian blue).
Results
Autopsy revealed a distinct yellow discolouration and thrombotic necrosis of the oral mucosa and almost the whole gastrointestinal tract, as well as similar changes in the adjacent internal organs. Considerably high levels of iron and chloride ions were detected in specimens of internal organs preserved during autopsy. Histopathological analysis performed with the use of staining specific for iron (Prussian blue) also confirmed the presence of iron in the examined tissues, especially in the intestines and liver.
Conclusions
Considering the above findings, it was concluded in the forensic report that the death of the woman was caused by the ingestion of iron chloride. The reported case of fatal intoxication is one of the few described in the literature, and its course implies that in the case of initially diagnosed intoxication with corrosive compounds, the possibility of using metal-containing poison should also be considered in the differential diagnosis. In addition to routine toxicological tests performed in fatal cases we also draw attention to the possibility of using specific staining protocols for microscopic specimens.
