title: Infantile fibrosarcoma in a child: a case report.
abstract: BACKGROUND
  Infantile Fibrosarcoma is a rare soft tissue tumor in infants and children mostly located in extremities. An infantile and adult form has similar histopathological patterns but survival prognosis is much better in infantile form. Recurrence of infantile fibrosarcoma is common but the rates of metastasis are less than 10 percent in children younger than five Years and 50 percent in children more than 10 years old.
  
  
  METHODS
  In this case report, we presented a nine years girl with a relapsing mass in her left hand. The pathologic findings showed sheets of spindle-shaped cells with suggested diagnose of infantile fibrosarcoma. She was successfully treated with combination of surgery and chemotherapy with a good outcome.
  
  
  CONCLUSIONS
  Infantile fibrosarcoma is a differential diagnose of soft tissue mass in infants and children. It has a good prognosis and distant metastasis is uncommon. Choice of treatment is surgery but chemotherapy and radiotherapy were useful in decrease metastasis.
