Mushroom poisoning is increasing worldwide, as well as the incidence of fatal mushroom
poisoning. Several new syndromes associated with mushroom poisoning have been described
in the literature. Notably, 1 of the newly identified mushroom poisonings is Russula subnigricans poisoning. R subnigricans can be classified as causing a delayed-onset rhabdomyolytic syndrome as patients
with this severe poisoning present with severe rhabdomyolysis, acute kidney injury,
and cardiomyopathy. However, there are only a few reports on the toxicity of R subnigricans. We recently treated 6 patients with R subnigricans mushroom poisoning, of whom 2 died. The 2 patients showed severe rhabdomyolysis,
metabolic acidosis, acute renal failure, electrolyte imbalance, and irreversible shock,
which caused their deaths. Mushroom poisoning should be considered in the evaluation
of rhabdomyolysis of unknown origin. In addition, in cases of mushroom poisoning with
severe rhabdomyolysis, R subnigricans poisoning should be promptly identified.
