[Hypochondrial euphoria].

After a brief survey of the casuistics, three patients presenting a peculiar clinical picture are described, combining a florid hypochondriac production of delusion on the background of a euphoric condition and drive. Arguments in favour of the relative independence of this type of endogenous affective-phasic psychosis are pointed out and the limited possibility of a condition of a mixture of manic-depressive psychoses are discussed. Of practical importance is the demarkation of the hypochondriacal euphoria from schizophrenia, abnormal personality and psychical reactions to events.
