Introduction: 25-year-old woman originary from China. Moved to Barcelona 2 years ago for her master studies. Not known personal or familiar psychiatric record. Admitted to the psychiatric ward due to a 3-month psychotic episode with delusional features including transportation delusions "people can travel into other dimensions"; megalomaniac delusions, "I communicate with a Buddhist divinity called Guan Yin", "I have the mission of rejuvenating the population"; nihilistic and Cotard-like delusions "people around is old and dead"; denial of lineage syndrome, intermetamorphosis syndrome and doppelgänger syndrome. Nohallucinatory featureswere present. Severe emotional and behavioural implications were associated. Objectives: To analyse the transcultural component of bizarre delusions in a Chinese patient. Methods: Somatic causes for psychosis were ruled out. Risperidone up to 6 mg was started and afterwards intramuscular paliperidone palmitate 150+100 mg was administered, suspending risperidone. Results: Psychotic symptoms remitted progressively during hospitalization, so that the patient was discharged after 1-month. Conclusions: 1. This patient presented polymorphous bizarre delusions, some of them related to the Chinese culture. 2. Psychotic contents are influenced by the cultural beliefs. In this case, Guan Yin divinity (from Chinese religion) acquires psychotic implications being part of the cultural background of the patient. 3. The denial of lineage syndrome, which can be misinterpreted as a Capgras syndrome, is one of the most common delusions in China. 4. Due to the one-child policy, Chinese population aging will be a forecasted problem. The patient expressed this concert in a megalomaniac delusional manner. [ABSTRACT FROM AUTHOR]
