Symptomatic gastric sarcoidosis in a patient with pulmonary sarcoidosis in remission

Sarcoidosis is a multisystem, non-infectious, granulomatous disease of unknown cause, characterised by histological evidence of non-caseating granulomas. Gastrointestinal (GI) involvement is uncommon, reported in <1% of patients with the disease. Herein, we present a rare case of isolated gastric sarcoidosis in a patient with latent pulmonary sarcoidosis and unexplained manifestations of GI disease, illustrating that clinical disease expression is variable; may be organ-specific; and, known disease latency confined to one organ does not exclude the possibility of active disease in another organ system. In patients with organ-specific sarcoidosis, whether active or in remission, presenting with GI symptoms, the possibility of gastric sarcoidosis should be considered. Oesophagogastroduodenoscopy and biopsy, when indicated, should be considered for definitive diagnosis.
