The clinical description of psychotrauma has undergone a huge change since the advent of the new versions of international classifications, in particular the DSM 5, which through basic clinical criteria (reliving/hypervigilance/avoidance), helps the clinician to make the diagnosis of post-traumatic stress disorder (PTSD). However, psychotrauma presents transonographic and transcultural characteristics, as it can take on different clinical pictures, essentially a psychotic picture, which can mislead the diagnosis and in this case the therapeutic management. Through a clinical vignette rich in clinical polymorphism, we will expose the different difficultes encountered, highlighting the need for an approach based on a multidimensional approach criteriological perhaps, but psychopathological and phenomenological certainly. Therefore, it is important that the clinician takes into consideration the cultural, social and biological dimension in order to guarantee a good management both with medication and psychotherapy.
