The stomach is the most common site of gut involvement by sarcoidosis, with prevalence estimated as high as 10%, although symptomatic GI disease is reported to occur in < 1% of sarcoidosis patients. Patients may present with epigastric pain, nausea, vomiting, weight loss, or even hemorrhage. Radiographic and endoscopic examinations have demonstrated a wide range of findings, including gastritis, nodular mucosal changes, ulcers, a linitis plastica appearance, and polyps. Definitive diagnosis requires gastric biopsy, even in patients with known sarcoidosis. Treatment with corticosteroids or other immunosuppressives is indicated for symptomatic relief. Surgical intervention has also been reported for such complicating features as gastric outlet obstruction, suspicion of malignancy, and hemorrhage.
