Abstract
Cases of paraquat poisoning have a high mortality rate, generally occurring due to accidental consumption or intentional use in suicide attempts. The objective of this study was to report the main clinical and medico-legal findings of a case of death due to exogenous paraquat poisoning in the State of Santa Catarina, Brazil. The victim was a 57-year-old woman with a history of suspected self-poisoning by the herbicide, which occurred 48 hours before hospitalization. The day after being admitted to the hospital, the victim died. Externally, the body was edematous, presenting an intense generalized yellow coloration (jaundice) that was striking. The blood test showed elevated liver biochemical markers. The victim presented chemical burns in the oral cavity. The main internal medico-legal findings consisted of pulmonary fibrosis, with hemorrhagic suffusions in regions of the lungs; congestion, jaundice, hepatic necrosis and areas with hemorrhagic punctate lesions in the liver; and diffuse hemorrhagic regions in the kidney parenchyma. The medico-legal findings in this case study were consistent with results presented by other researchers. The victim's cause of death was determined to be multiple organ failure due to exogenous poisoning by paraquat
