title: Solid-pseudopapillary tumor of the pancreas (Frantz tumor) in children: report of four cases and review of the literature.
abstract: BACKGROUND
  Solid-pseudopapillary tumor of the pancreas (SPT) is an exceptionally rare neoplasm in children. Its origin remains enigmatic. It is of low malignant potential and occurs most frequently in young females.
  
  
  METHODS
  A cumulative review of the tumor's clinicopathological characteristics from the world's literature is presented. The clinical course, pathohistologic data and outcome of surgery of four Austrian children treated at the general hospital of Vienna are analyzed.
  
  
  RESULTS
  Between 1987 and 1999, four girls (age: 12--16 years) with SPT were diagnosed at our institution. All patients presented with an abdominal mass and uncharacteristic abdominal pain. Two tumors were located in the tail, one in the body and tail and one in the head of the pancreas (diameter: 7--15 cm). Surgical procedures included three distal pancreatectomies and one partial duodenopancreatectomy (Whipple procedure). One patient had two recurrences with metastases that could only be partially resected. Chemotherapy was initiated for this patient. In the follow-up period (range: 6 months to 12 years) all patients are alive with no evidence of recurrence.
  
  
  CONCLUSIONS
  SPT is a rare differential diagnosis of a pancreatic mass in children. It is mandatory to establish this diagnosis since complete surgical removal of the tumor even in case of metastases or local invasion offers an excellent prognosis.
