A rare bone disorder affecting the tibia and fibula
Osteofibrous dysplasia is a rare, benign bone disorder that primarily affects the tibia and fibula in children and adolescents. It is characterized by the replacement of normal bone with fibrous tissue and immature woven bone. This condition is also known as ossifying fibroma of long bones and is considered a developmental anomaly rather than a true neoplasm.
Presentation[edit]
Osteofibrous dysplasia typically presents in the first two decades of life, with most cases diagnosed in children under the age of 10. The condition is more common in males than females. Patients often present with a painless swelling or deformity of the affected limb. In some cases, there may be associated pain or tenderness, particularly if there is a pathological fracture.
Pathophysiology[edit]
The exact cause of osteofibrous dysplasia is unknown, but it is thought to be a developmental disorder rather than a neoplastic process. The condition is characterized by the replacement of normal cortical bone with fibrous tissue and immature woven bone. Histologically, the lesions show a mixture of fibrous stroma and trabeculae of woven bone, often with osteoblastic rimming.
Diagnosis[edit]
Diagnosis of osteofibrous dysplasia is typically made based on clinical presentation, imaging studies, and histological examination. X-ray imaging of the affected bone usually shows a well-defined, radiolucent lesion with a sclerotic border. Computed tomography (CT) and magnetic resonance imaging (MRI) can provide additional detail about the extent of the lesion and its effect on surrounding structures. A biopsy may be performed to confirm the diagnosis and rule out other conditions such as adamantinoma.
Treatment[edit]
The management of osteofibrous dysplasia depends on the severity of the symptoms and the risk of complications. In many cases, observation and regular follow-up are sufficient, especially if the lesion is asymptomatic and not causing significant deformity. Surgical intervention may be necessary if there is significant pain, deformity, or risk of fracture. Surgical options include curettage, bone grafting, or, in severe cases, resection of the affected segment and reconstruction.
Prognosis[edit]
The prognosis for patients with osteofibrous dysplasia is generally good, as the condition is benign and does not metastasize. However, there is a risk of recurrence after surgical treatment, and in rare cases, the condition may progress to adamantinoma, a malignant bone tumor. Long-term follow-up is recommended to monitor for potential complications.
