title: An unusual case of collagenous gastritis in a middle- aged woman with systemic lupus erythromatosis: a case report.
abstract: BACKGROUND
  Collagenous gastritis is a rare histopathologic disease. It is characterized by marked subepithelial collagen deposition with associated inflammatory infiltrate. It is considered an uncommon disease among the general population. Collagenous gastritis without colonic involvement is an extremely rare disease. It is not known to be associated with systemic lupus erythromatosis. This is the first report of this type of association.
  
  
  METHODS
  We present a 47-year-old woman from southeast Asia with dyspepsia and mild anemia. Her past medical history was significant for systemic lupus erythromatosis, autoimmune hemolytic anemia as well as hypothyroidism. Her gastroscopy and colonoscopy results were normal from an endoscopic point of view. However, the histopathology showed collagenous gastritis.
  
  
  CONCLUSIONS
  To the best of our knowledge, this is the first case reported of a patient with systemic lupus erythromatosis associated with collagenous gastritis. Further studies are needed to evaluate the association between both diseases from a pathophysiological and immunological perspective.
