[Hysterical psychoses revisited].

The author, after reviewing the literature about hysterical psychosis, briefly presents some of the surveys made in this area. The point of departure are the Hollender and Hirsh criteria for hysterical psichosis defined in 1964. These authors assumed that the clinical picture responds to a psychopathological entity which results from a single process. The other surveys presented try to prove this concept through case report and epidemiological research. The author concludes leaving this concept as an open question, suggesting that this could be a pathway for further research.
