Résumé
Ce rapport de cas décrit l’évolution clinique d’un homme adulte suivi en psychiatrie légale et communautaire, présentant une histoire complexe de trouble psychotique, de traumatisme développemental, de polytoxicomanie sévère et de désinsertion sociale prolongée. Le caractère original de ce cas réside dans l’émergence progressive de phénomènes obsessionnels-compulsifs atypiques lors des phases de réinsertion psychosociale structurée, phénomènes qui s’intensifient dans les contextes de demandes relationnelles et institutionnelles multiples, puis s’atténuent lorsque le patient se retire de certains engagements ou cadres imposés. Les symptômes dominants incluent des ruminations intrusives persistantes, des comportements ritualisés d’autoapaisement à visée somatique, ainsi que des conduites répétitives peu modulables par le raisonnement. Le diagnostic différentiel, les interventions thérapeutiques mises en place et l’évolution clinique sont discutés à la lumière des modèles contemporains des troubles obsessionnels-compulsifs, du stress post-traumatique complexe et des trajectoires de réinsertion chez des patients psychotiques judiciarisés. Ce cas met en évidence l’importance de considérer l’environnement psychosocial comme un facteur dynamique pouvant majorer ou atténuer les symptômes obsessionnels-compulsifs, indépendamment de la stabilité psychotique apparente.

Abstract
This case report describes the clinical course of an adult man followed in forensic and community psychiatry, presenting a complex history of a psychotic disorder, developmental trauma, severe polysubstance use, and prolonged social marginalization. The originality of this case lies in the progressive emergence of atypical obsessive-compulsive phenomena during phases of structured psychosocial reintegration. These phenomena intensify in contexts of multiple relational and institutional demands and attenuate when the patient withdraws from certain commitments or imposed frameworks. Predominant symptoms include persistent intrusive ruminations, ritualized somatic self-soothing behaviors, and repetitive actions that are poorly modifiable through reasoning. The differential diagnosis, therapeutic interventions, and clinical evolution are discussed in light of contemporary models of obsessive-compulsive disorders, complex post-traumatic stress disorder, and reintegration trajectories among justice-involved patients with psychotic disorders. This case highlights the importance of considering the psychosocial environment as a dynamic factor that may exacerbate or mitigate obsessive-compulsive symptoms, independently of apparent psychotic stability.
