Fatality due to paraquat intoxication: confirmation by postmortem tissue analysis.

S E Conradi, L S Olanoff, W T Dawson

    American Journal of Clinical Pathology
    |November 1, 1983
    PubMed
    Summary

    A patient unknowingly ingested fatal paraquat, likely in illicit alcohol. Diagnosis was confirmed postmortem due to high tissue paraquat levels, despite negative initial toxicological screening for this herbicide poisoning.

    Area of Science:

    • Toxicology
    • Forensic Pathology
    • Clinical Medicine

    Background:

    • Paraquat herbicide poisoning can be fatal.
    • Illicitly produced alcohol may be contaminated with toxic substances.
    • Early diagnosis of paraquat poisoning is crucial for treatment.

    Observation:

    • A case report details a patient with suspected paraquat intoxication.
    • Initial blood and urine tests for paraquat were negative.
    • The patient presented with symptoms typical of paraquat poisoning.

    Findings:

    • Postmortem examination revealed high paraquat concentrations in major organs.
    • Histopathologic changes were observed in the lungs, liver, and kidneys.
    • The unique toxicologic profile of paraquat was noted.
