Two children with childhood asthma, without prior evidence of psychosis, manifested transient and completely reversible psychotic episodes in the course of psychotherapy. The dynamic conflicts which precipitated the transient psychosis would previously have precipitated an asthmatic episode had aggressive

conflicts remained repressed. A brief review of the literature on the subjects of asthma and aggression and psychosis and asthma is presented. An attempt is made to explain the relationship between the observed psychotic episodes, the observed asthmatic episodes, and the vicissitudes of the aggression in these patients.
