Calcium chloride poisoning: an autopsy case report and histologic features.

Calcium chloride, which is commonly used in de-icing agents and desiccants, is known for the potential harm it can cause through skin contact, oral ingestion, or intravenous administration. The current paper reports on an autopsy case of a 68-year-old woman who died after ingesting an unknown substance. Histopathological examination revealed coagulative necrosis in the esophagus and ionized blood calcium levels that were significantly higher than normal. Calcium chloride was detected in the contents of the water bottle collected at the scene. These results are expected to make a significant contribution to the limited literature on fatal outcomes from calcium chloride ingestion, while emphasizing the need for heightened awareness and education about the risks of commonly available chemicals.
