title: Melena as presentation of primary small intestine inflammatory myofibroblastic tumor in an adult woman. A case report.
abstract: BACKGROUND
  Inflammatory myofibroblastic tumor (IMT), also known as inflammatory pseudotumor, plasma cell granuloma or inflammatory myofibroblastoma, is characterized histopathologically by myofibroblastic spindle cells with inflammatory cell infiltrates ( plasma cell, lymphocytes and eosinophils). Inflammatory myofibroblastic tumor is tipically seen in children or young adults and is most commonly localized in the lung, but it can occur anywhere in the body.
  
  
  METHODS
  We present a case in a young woman with severe acute G.I. bleeding, an uncommon presentation of IMT in adults. The patient was admitted to the emergency department for melena. MRI showed a distal jejunum hypervascular mass. Other exams were negative. Surgical excision was recommended, so the patient underwent surgery with complete removal of the tumoral mass. No adjuvant therapy was employed and the patient is asymptomatic after 6 months of follow-up.
  
  
  CONCLUSIONS
  IMT is an rare lesion that mimics malignancy and is accompanied by various clinical manifestations. The treatment of choice is believed to be complete surgical excision and long term follow up.
