A systematic search was performed on PubMed, Biblioteca Virtual de Salud, Science Direct, World Wide Science, SCIELO and DOJA, taking into consideration only case reports and case series studies for Fregoli Syndrome in English, Spanish and Portuguese published up to December 31h 2022. We follow the PRISMA methodology and we used RAYYAN web tool to select the right items for our searchand we found the Fregoli syndrome is a delusional disorder, which occurs more in adults, most cases correspond to both men and women in equal proportion, no age of onset has been established, therefore, it can appear at any stage of life. In most cases it usually occurs in association with other delusional disorders such as Cotard's syndrome, Capgras, Erotomania, Intermetamorphosis and subjective doubles, although isolated cases have also been described with schizophrenia. The pharmacological treatment in most cases includes the use of antipsychotics such as chlorpromazine, risperidone and in very few cases the use of cognitive-behavioral psychotherapy.<br>
