Abstract
Giant cell tumors of bone rarely occur in facial bones. As compared with other benign tumors, this tumor is aggressive and has a risk of local recurrence and late malignant changes with metastasis. We report a rare case of giant cell tumor in the mandible of a 4-year-old boy. He was referred to our department because of a radiolucent lesion in the right posterior mandible. Clinical examination revealed a diffuse painless swelling on the right side of the mandible. Under a clinical diagnosis of a tumor in the right side of the mandible, the tumor was extirpated. On histopathological examination, the tumor showed a large number of giant cells and proliferation of spindle cells. The patient has shown no evidence of recurrence for 1 year 6 months.
