[Granulomatous tuberculoid gastritis (author's transl)].
The authors report seven cases of tuberculoid granulomatous gastritis. Tuberculosis was the cause in three cases. Bilharziasis was the cause in two cases. Sarcoidosis was identified in one patient. In only one case was the etiology undetermined. This seems rare. Some of these form should be compared with experimental tuberculoid granulomatous gastritis, obtained after sensitisation to foreign substances included in the gastric mucosa. The organisation of the epithelioid and giant cell granuloma corresponds to an immune defence reaction of the stomach, bringing into play immunoglobulins IgG and IgM to lead to the formation of antigen antibody complexes in these tissues.
