The final diagnosis
of granulomatous gastritis is based on morphological findings and
detailed clinical history and laboratory data.
Clinicians must provide the following clinical details to the pathologist - History of immunosuppression , intake of drugs, past history of tuberculosis, sarcoidosis, Crohn's etc. Macrosopically there is thickening of the gastric wall (D/D infiltrating carcinoma).

- Miscellaneous: Multiple granulomas are observed in sarcoidosis, Whipple's disease and vasculitis-associated cases. |

A
clinicopathologic study of 42 patients with granulomatous gastritis. Is
there really an "idiopathic" granulomatous gastritis?Am
J Surg Pathol. 1996
Apr;20(4):462-70. "(a) in most cases of granulomatous gastritis, a diagnosis of Crohn's disease or sarcoidosis could be established; (b) the background inflammatory pattern was helpful in suggesting a diagnostic category for granulomatous gastritis; (c) granulomatous gastritis is not associated with H. pylori per se; however, if known cases of Crohn's disease and sarcoidosis are excluded, an association between H. pylori and granulomatous gastritis cannot be ruled out; and (d) IGG, if it exists, is extremely rare.
