It is our purpose to ponder over the psychoanalytic clinic of psychoses in mental health institutions, a theme that, on the one hand, raises questions and dilemmas to the psychoanalytic clinic method, and on the other, contributes to renew the Freudian discovery. Firstly, we will approach the psychoses' clinic, and after that, we will discuss the social and clinical extension of psychoanalysis; then, we shall focus on the psychoanalytical practice in mental health institutions. In this last segment, we will point out the testimony of psychoanalysts who act in such institutions; they point out to a practice by many whose focus is on a subject clinic. The mode of subjective production occurs through "trivialization", a precious maneuver used by analysts and other technicians who make up the institutional team, in order to neutralize the delirium action. Such procedure requires from the analyst a certain degree of invention, humor and detachment of the wish to interpret.
