[Pseudo-polypoid forms of crohn's disease (author's transl)].

Crohn's disease with a predominantly pseudopolypoid presentation is a rare form. The inflammatory polyps are of highly variable topography. They may be located in the colon and the ileum. There are diffuse and localised forms. This pseudopolypoid form of Crohn's disease poses, in addition to diagnostic problems, pathogenic questions, integrating these findings within the context of nonspecific reactions of the colon, secondary to an ulcerating process which may be specific.
