[The mycetisms and their relevancy in medicine.]

Poisonous mushrooms play an important role in public health, since the poisonings caused by their toxins have very high morbidity-mortality rates. No real data are available on this problem because diagnosis is often difficult. This work points out the important role of poisonous mushrooms. An analysis is included of the clinical features of the most important mycetisms, the mushrooms that produce them and the toxins that cause this pathology. A guide to aid clinical doctors in the diagnosis and treatment of mycetisms and recomendations to prevent these poisonings are provided.
