[Amanita proxima poisoning: a new cause of acute renal insufficiency].

To our knowledge Amanita proxima poisoning has never been reported. Amanita proxima is a mushroom seldomy encountered, similar to a common and edible species: Amanita ovoïdae. During October 1992, we had the opportunity to care for five cases of intoxications with Amanita proxima. In all cases early digestive disorders, cytolytic hepatitis and acute renal failure were noted. Outcome was favourable for all patients within three weeks with total recovery of both renal and hepatic functions with symptomatic treatment. Temporary dialysis was required in four patients.
