Currently, treatment modalities for narcissistic personality disorder are limited in both availability and effectiveness. There is no distinct psychotherapeutic guideline for narcissistic personality disorder and no unified recommendation of psychotherapies and techniques that can be used. This article aims, on the one hand, to present some general recommendations in narcissism psychotherapy, found in the specialized literature, and on the other hand – to particularize on a clinical case some techniques that do not belong to a particular therapeutic orientation, but that have proven their effectiveness in working with this type of clients. The final aim of the whole endeavor is to identify the first milestones/frameworks of a future psychotherapeutic guide for narcissistic personality disorder, useful for clinical psychologists and psychotherapists, aiming at: decreasing selfinflation, decreasing the degree of egocentricity, increasing the degree of empathy and reducing the level of preoccupation with building a grandiose self-image.
