[Prostitution in adolescence: interfaces with the family institution].

Research carried out aiming at learning and analysing the context and significance of the dynamics in the family institution and its interfaces with the prostitution of adolescents. Data collection was carried out by means of life story interviews, and the content of the speeches underwent thematic analysis. We found a wide gap caused by the lack of dialogue and by how situations of abandonment, mother's death and life with family members being not a biological daughter of one of the parents have been experienced, breaking up with trust, respect and affect relationships, thus causing the loss of individual and collective identity. Violence within the family was identified through situations of sexual abuse, negligence and physical violence, thus making evident a true school of disrespect, abuse of power and gender/age hierarchy.
