title: Haemolytic anaemia secondary to arsenic poisoning: a case report.
abstract: We report the case of a 56-year-old white man who presented at the Emergency Department for evaluation of dark-red urine. Rapid development of acute renal failure and haemolytic anaemia initially elicited the hypothesis of a haemolytic-uremic syndrome. A previous exposure to a gas mixture containing arsenic and copper was later recognized as the probable aetiology while other differential diagnoses were excluded. Chelating treatment was promptly initiated before laboratorial confirmation of arsenic and copper poisoning. Renal and haematological recovery was gradually observed and the patient survived with no sequelae.
