[Morphology of a paraquat poisoning]

The predominant pathomorphological findings in acute lethal paraquat intoxication are interstitial and alveolar edema, as well as structural changes of the pulmonary architecture, probably as a result of damage of the surfactant by peroxides. The typical histopathological changes are illustrated in a suicide case in which paraquat was used. An oligodendroglioma of the left frontal lobe was the organic cause of suicide.
