Extract

To the Editor: Delusional misidentification syndrome (DMS) consists of a number of pathological conditions in which a person has a belief involving misidentification of a person, place, or object; this belief is adhered to in spite of clear evidence refuting it.1 It includes Capgras syndrome, Fregoli syndrome, reduplicative paramnesia, and inter-metamorphosis. Reverse inter-metamorphosis is a variant of inter-metamorphosis in which patients believe that they themselves are being or have been transformed into another entity. Clinical lycanthropy is a rare form of reverse inter-metamorphosis wherein patients believe that they are undergoing transformation or have transformed into a non-human animal. A case of such a delusional misidentification involving the Self is presented here.
