The case of a motherless paranoid patient who finds in evacuation a way of minimizing the invasion of the Other, and who relates to be relieved when letting feces out, led us to the hypothesis that the extraction of the object a, the feces, is an attempt to carry out an operation in the real that wasn't accomplished in the symbolic. After analyzing the function of his delusion, we concluded that the construction of a delusional metaphor, which was possible through the identification with an ideal signifier, barres the jouissance of the Other and helps the subject, at least temporary, to localize jouissance in an object outside the body. This hypothesis was also verified in the light of the conceptualization of grief as losing a piece of oneself, in case of an impossible mourning.
