A fibrosarcoma is a cancerous soft tissue tumor that originates in the connective fibrous tissue found at the ends of arm and leg bones; it then spreads to other surrounding soft tissues. Fibrosarcoma usually affects either a lower leg or arm.

There are two forms of fibrosarcoma:

  • Infantile or congenital fibrosarcoma is the most common soft tissue sarcoma found in children under one year old. This form of fibrosarcoma is usually slow-growing, and tends to be more benign than fibrosarcoma in older children, which behaves more like the type found in adults.
  • Adult form fibrosarcoma can occur in older children and in adolescents, roughly between the ages of 10 and 15. It is more aggressive than the infantile form and generally involves more complex treatment.
