title: Childhood hemangiopericytoma.
abstract: BACKGROUND
  Hemangiopericytoma (HPC) is an uncommon tumor of childhood.
  
  
  RESULTS
  This paper summarizes our experience with 5 children with histologically proven HPC treated in a single institution, including 2 cases of congenital HPC. This tumor has varying clinical presentations and biological behavior. Congenital tumors have a better prognosis. Chemotherapy and radiotherapy had little effect on outcome.
  
  
  CONCLUSIONS
  Complete surgical excision is the treatment of choice.
