title: [An unusual case of duodenal sarcoidosis].
abstract: BACKGROUND
  Sarcoidosis is a systemic granulomatous disorder of unknown aetiology. It may rarely affect the gastrointestinal tract.
  
  
  METHODS
  We reported a 54-year-old woman with a delayed diagnosis of duodenal sarcoidosis. She presented with gastric and right upper abdominal pain associated with vomiting and marked weight loss. Abdominal computed tomographic scan showed non-compressive retroperitoneal lymph nodes and histological examination revealed non-caseating epithelioid granulomas typical of sarcoidosis. Diagnosis of duodenal sarcoidosis was obtained at the third gastroscopy. The patient's condition improved quickly with corticosteroid therapy.
  
  
  CONCLUSIONS
  Gastrointestinal sarcoidosis should be looked for in patients with digestive symptoms and another sarcoid localisation. Furthermore, it is important to repeat gastroscopy to confirm diagnosis because treatment improved most patients.
