title: [Pathology of the Crohn's disease of colon (author's transl)].
abstract: The examination of 43 postoperative specimens and of 51 biopsic specimens of the rectum concerning colic Crohn's disease (MCC) confirm the known macroscopic and histologic characteristics of this disease. The epithelioid and gigant cell granuloma is rarely observed in the biopsic specimens of the rectum, and it is not always observed even on post operative specimens (only in 40% of the cases). The other characteristics and in particular the small "serous lymphohistiocytic perivascular infiltrates" should be taken into account when making the diagnosis. At the present time, there are still a certain number of forms of ulcerative colitis which cannot be classified, and the characteristics of which are both those of the MCC and of the RCUH.
