Granulomatous gastritis as a diagnostic problem between sarcoidosis and other granulomatous disorders.

A 59-year-old man, who suffered from achlorhydria and epigastric pains but was otherwise asymptomatic, was found to have a granulomatous lesion on the gastric mucosa suggesting sarcoidosis or a localized form of Crohn's disease. No sign of involvement of terminal ileum or rectum was detected. A liver biopsy specimen showed slight changes suggestive of granulomatous inflammation, but other signs of generalized sarcoid manifestations were absent. The patient was successfully treated with corticosteroids.
