[Post-traumatic grief and the need for ritual in therapy].

This clinical history retraces the treatment of an Ivorian man presenting with a state of post-traumatic mourning following the assassination of his family ten years ago, in a context of crisis. The aim is to illustrate the need for flexibility in the therapeutic framework in this mourning process, which is complicated or even prevented by psychotraumatic symptoms and the absence of rituals. The transcultural approach initiates here a first evolution in the patient's symptomatology.
