[Work of the so-called phantom in the unconscious and psychosomatics. Apropos of psoriasis].

The theory of "ghost" in the heart of the unconscious relates the precocious psychic legacy of mental misfunctioning through the unconscious to unconscious relationship with a relative inhabited by a mourning that has not been worked through. These misfunctionings can express themselves thanks to various psychopathological demonstrations, but through psychosomatical illnesses as well. As shown by the authors in some cases of psoriasis: determinism that could associate--a genetical predisposition of the future patient,--a notion of family or personal history having to do with events such as burns, fire.
