title: Spontaneously identified gastric sarcoidosis: a report of three cases.
abstract: Sarcoidosis is a systemic granulomatous disease, frequently involving the lungs, lymph nodes, eyes and skin. Gastric sarcoidosis is very rare. We report three patients diagnosed initially with gastric sarcoidosis. Two had no other identified involvement, and one had involvement of the lungs and hilar lymph nodes. Gastroscopy was performed because of abdominal discomfort or as a follow-up examination for partial gastrectomy. This revealed atrophic lesions with nodular mucosal changes in the antrum and granular mucosa, and residual gastritis was found at the site of gastroduodenal anastomosis. Non-caseating epitheloid-cell granulomas were found in all patients following histological analysis. Gastroscopy and histopathological findings in gastric mucosal biopsy samples from suspicious sites are essential in establishing an accurate diagnosis of gastric sarcoidosis.
