Disseminated sarcoidosis: a case report

Sarcoidosis is a systemic granulomatous disease of unknown etiology, most frequently involving the lungs, lymph nodes, spleen, liver, eyes and skin. Gastrointestinal sarcoidosis is uncommon, with rare histological documentation of noncaseating granulomas. Bone marrow sarcoidosis is also infrequent, and we are only aware of one case of documented gastric and bone marrow sarcoidosis in the same patient, which was diagnosed at autopsy. We herein report a case of endoscopic biopsy proven gastric sarcoidosis in a patient with systemic sarcoidosis with known hepatic and bone marrow involvement. To our knowledge this is the first description in a living patient of gastrointestinal and bone marrow involvement of systemic sarcoidosis.
