title: Jejuno-jejunal invagination caused by epithelioid sarcoma: a case report.
abstract: BACKGROUND
  Jejuno-jejunal invagination is a rare condition and is usually caused by a benign lesion. We describe the case of a patient with a jejunal epithelioid sarcoma. Epithelioid sarcoma is a rare histologic subtype of sarcoma and few cases have been published.
  
  
  METHODS
  A 70-year-old Caucasian man presented with vomiting and anemia. A jejuno-jejunal invagination was diagnosed and the patient underwent surgery. An epithelioid sarcoma of the wall of the jejunum was found on the invaginated ansa.
  
  
  CONCLUSIONS
  To the best of our knowledge, an epithelioid sarcoma has never been reported to arise at the wall of the proximal jejunum or to present with jejuno-jejunal invagination.
