Abstract
In our clinical work, we have often encountered patients with psychosomatic diseases who sought psychiatric help. In this paper, we will review the theoretical concepts of aggression and their connection to the occurrence, symptoms and course of psychosomatic diseases. Is aggression an emotion or a personality trait, how is it presented in the psychoanalytic process? Case reports from our clinical practice show different manifestations of aggression in patients with psychosomatic disorders and indicate difficulties in psychotherapeutic work, especially in relation to countertransference feelings.
