Introduction: Fibrous Dysplasia is a benign intramedullary fibro-osseous lesion that are reported to represent approximately 5%-7% of benign bone tumor. Treatment of fibrous dysplasia include bisphosphonates therapy and surgical procedures. Case Report: A 9-year-old girl presented with a mass on her left forearm 2 years ago. Primary resection by curettage was performed and patient did not and one year after the surgery, the mass recurred and patient complaint about lump and deformity on her left forearm. A limb salvage surgery by intercalary resection was performed to remove the tumor and the defect was filled with vascularized fibular graft from the right leg. Seven- month follow up show no sign of recurrence and patient underwent surgery to remove the implant. Discussion: Fibrous dysplasia represents a dysplastic disorder of bone characterized by solitary or multifocal polyostotic intramedullary lesion composed of proliferation of fibroblastic spindle cells. Treatment of fibrous dysplasia include conservative treatment and surgical procedures may be required for correction of deformity, prevention of pathologic fracture and/or eradication of symptomatic lesion. The free vascularized fibular graft is particularly suited for reconstruction of large forearm defects because the fibula matches the radius and ulna in size and shape with studies that shown healing rate of 89%. Conclusion: Fibrous Dysplasia is a benign intramedullary fibro-osseous lesion that are reported to represent approximately 5%-7% of benign bone tumor. The most common clinical symptom is swelling or deformity of the affected site. Treatment of fibrous dysplasia using vascularized fibular graft may be an effective option.
