CORTESE, Silvia; RISSO, Marina  and  TRAPASSI, J. Horacio. Amanita phalloides poisoning: series of three cases. Acta toxicol. argent. [online]. 2013, vol.21, n.2, pp.110-117. ISSN 1851-3743.

We present a series of three cases of Amanita phalloides poisoning in adult patients admitted during the period 2010 - 2011. Two patients were males of 40 and 75 years old, and the third was a woman of 65 years old. In all cases, the poisoning was associated with the home practice of collecting wild mushroom for cooking (activity traditionally carried out for more than 10 years in all cases). Mushroom collection was carried out in areas of oak trees for one case, and in areas of chestnuts trees in the two other cases. In all three cases the admission took place between 16 and 36 hours from intake. All three patients developed diarrhea, liver disease and liver failure without encephalopathy. All patients received treatment with activated charcoal (serial administration), duodenal aspiration and intravenous penicillin. Liver transplantation was necessary in one case. There were no hepatic sequelae in any patients. Conclusions: The practice of collecting wild mushrooms for human consumption is a risky habit if performed by people untrained in recognition of toxic species. While poisoning with A. phalloides is uncommon, its high mortality makes indispensable its early recognition and treatment by physicians.
