An Unusual Cause of Abdominal Pain: Mesenteric Lymphadenopathy Secondary to Sarcoidosis Without Pulmonary Involvement.

Sarcoidosis is a systemic disease that affects multiple organs in the body but rarely affects the gastrointestinal (GI) tract. The symptoms of GI sarcoidosis may be nonspecific or silent. Often, it is discovered on computed tomography (CT) or esophagogastroduodenoscopy (EGD), and a biopsy is needed for diagnosis. Initial management is typically with prednisone; however, here, we present a rare case of GI sarcoidosis with mesenteric lymphadenopathy in the absence of pulmonary involvement, diagnosed via biopsy and treated successfully with methotrexate.
