In this article, we will examine in three stages some ambiguous facts encountered by professionals during a practice in a transcultural clinic. The first step concerns the interculturality of the concepts and the reactions of the migrant, which would undermine the professional and oblige him to question himself, to think of his clinical position and finally to work on the resulting negative cultural countertransference. The second stage will concern the actual indication of care in this context and we will choose to mobilize ethnopsychanalysis for this purpose. Finally, it will be necessary to reflect on the clinical and psychopathological perspectives that emerge from the clinical material. We will thus set the stage for a conceptualization in the psychopathology of a demigrant or remigrant family in suffering, or as a demigrant or remigrant patient, based on the case of a teenage victim of sexual abuse. We shall see that it is on the occasion of a return of the family in Cameroon and the intrusion of a traditional practice by the grandmother (traditional test of virginity) that the first traumatic event lived in France will make return after blow. This situation would shed light particularly on the difficult question of the always possible shock between two therapeutic cultures.
