    Kveim tests were done in forty-eight patients with Crohn's disease. Of forty-five with definite or probable Crohn's disease, twenty-three had a positive Kveim test. This finding could be explained:

    (1) By cross-reactivity between sarcoidosis and Crohn's disease antigens;

    (2) By an aetiological agent common to the two diseases, or

    (3) By a property of the Kveim test material used in testing.
