Among the delusional misidentification syndromes, Capgras is the most common delusional disorder. Is characterized by the belief that a person, usually related to the patient, has been replaced by an impostor. In a more rare presentation, delusion affects the recognition of the self, either his physical or his psychological identity. In this paper, the authors aim to describe a clinical case of false recognition of the patient's own physical identity. The patient was diagnosed with a Schizoaffective Disorder. The authors also describe summarily the different misidentification syndromes.
