Sarcoidosis is a multisystemic disease characterized by chronic non-caseating granulomas of unknown origin. Gastric involvement due to sarcoidosis has been reported rarely. Our patient is a 48-year-old man with involvement of both lung and stomach. Gastric sarcoidosis should be considered in patients with sarcoidosis who have gastric symptoms, and also while the similar gastric symptoms may also be seen in gastric carcinoma and peptic ulcer patients, gastric sarcoidosis should also be considered in the differential diagnosis of these diseases.
