[Frequency and pathogenesis of epitheloid cell granuloma in Crohn's disease (author's transl)]. 1979

P Schmitz-Moormann, and H Malchow, and B Miller, and J W Brandes

12% of the rectal biopsies (19% of the patients) showed epitheloid cell granulomas in clinically definite Crohn's disease. In colonic biopsies such granulomata were visible in 14% (22% of the patients). Granulomata were scarcely seen in normal or slightly inflamed mucosa. They were mostly found together with crypt abscesses and/or erosions and ulcers. The combination of local inflammation around crypts and crypt abscesses is rather characteristic for Crohn's disease. The inflammatory colonic alterations, visible in crohon's disease, may have the following pathogenetic sequence: Local colitis-crypt abscess--destruction of the crypt with proliferation of enlarged histiocytes--transformation histiocytes to epitheloid cells and Langhans cells--epitheloid cell granuloma.

D003424 Crohn Disease A chronic transmural inflammation that may involve any part of the DIGESTIVE TRACT from MOUTH to ANUS, mostly found in the ILEUM, the CECUM, and the COLON. In Crohn disease, the inflammation, extending through the intestinal wall from the MUCOSA to the serosa, is characteristically asymmetric and segmental.
