What is Non-Ossifying Fibroma?

In this blog, we’ll be providing an overview of a non-cancerous tumor we treat at Baylor Scott & White Greater Dallas Orthopaedics called Non-Ossifying Fibroma. Non-Ossifying Fibromas occur in between 20% - 40% of healthy children and are rarely harmful.

These non-cancerous tumors differ from other fibromas in that they have no chance of becoming cancerous over time. They are typically small, and despite tenderness and swelling, are benign. They present most frequently in the legs, but may appear on other long bones.

Non-Ossifying Fibromas

At the occurrence rate of 20-40% of healthy children between the ages of 10 to 15 we mentioned previously, Non-Ossifying Fibromas are the most common benign bone tumors in children. 


What are the Causes of Non-Ossifying Fibroma?

An exact cause is not known and there are no known risk factors. They rarely appear simultaneously, and multiple non-ossifying fibromas are associated with neurofibromatosis and Jaffe-Campanacci syndrome.


Who is Most Affected by Non-Ossifying Fibroma?

Non-Ossifying Fibromas most often affect children, and are twice as common in boys for reasons that aren’t fully known. Seeing as these tumors rarely cause symptoms, most people are unaware they’ve dealt with them. 


What are the Symptoms of Non-Ossifying Fibroma?

Non-Ossifying Fibromas rarely cause symptoms outside of tenderness or mild swelling. If the tumor is large enough, it may weaken the bone it’s attached to, causing a fracture. In the case of considerable pain, the child is likely feeling the fracture rather than the tumor itself. 


How is Non-Ossifying Fibroma Treated?

Due to its painless nature, most Non-Ossifying Fibromas are discovered by x-rays taken for other reasons. Removal of Non-Ossifying Fibroma is rarely necessary, but if it continues to grow it may be removed through surgery to the avoid weakening or fracturing of the bone. 

We hope this overview of Non-Ossifying Fibroma was insightful and enlightening.
