Fibrosarcoma of the oral cavity

Abstract

Fibrosarcoma has been defined as a malignant tumor of the fibroblasts that shows no other evidence of cellular differentiation and is capable of recurrence and metastasis. Fibrosarcomas are rare but may occur anywhere in the body, most commonly in the retroperitoneum, thigh, knee and distal extremities. Fibrosarcoma is uncommon in the head and neck region and constitutes about 1% of all the malignancies affecting the human race. Of all the fibrosarcomas occurring in humans, only 0.05% occurs in the head and neck region. Of this, almost 23% is seen in the oral cavity. Fibosarcomas generally have a poor prognosis and the overall survival rate is 20-35% over a period of 5 years.
