Paraquat tongue is a rare manifestation of paraquat poisoning. This study reports a case of multiple ulcerations in the tongue of a 31-year-old depressed man who attempted suicide by ingesting a paraquat solution. Chest radiography showed diffuse ground glass opacities of both lungs with a thickening of the intralobular interstitium, compatible with interstitial pneumonitis. Urine paraquat was 10mg/mL. The patient was treated with an immediate detoxification by gastric lavage, active charcoal, charcoal hemoperfusion, pulse therapies of cyclophosphamide (15mg/kg/day for 2 days) and methylprednisolone pulse therapies (1g/day for 3 days), followed by prolonged dexamethasone therapy (20mg/day for 14 days), resulting a favorable prognosis. Furthermore, early intensive detoxification, the mainstay treatment, proved to effective in our case.
