Fibrosarcoma is a rare non-epithelial malignant tumor in the oral cavity. We describe a case of intraosseous fibrosarcoma of the mandible in a 37-year-old man. Diffuse swelling of the left side of the mandible and hypesthesia of the left side of the lower lip were present. X-ray examination revealed a poorly defined radiolucent lesion in the left side of the mandible. Histologically, the tumor was composed of atypical spindle cells resembling fibroblasts. There was no evidence of metastasis to the regional lymph nodes. Histopathological examination indicated that the tumor arose within the central portion of the mandible. There has been no evidence of recurrence as of 4 years 6 months after surgery.
