Osteofibrous Dysplasia is a rare benign bone tumor that typically develops in children and adolescents. Usually, it develops in the middle of the shin (tibia), although it can also develop in the fibula and the long bones of the arm.
Osteofibrous Dysplasia makes up less than 1% of all bone tumors, typically appearing in patients under 20 years of age. The tumor develops as a child grows up, but this growth slows or stops once bone development is complete.
Osteofibrous Dysplasia is often discovered through x-rays performed to diagnose a separate issue, as in many cases, no symptoms are present to indicate the presence of the tumor. When symptoms do appear, they may include swelling or pain where the tumor is located, fractures in parts of the bone weakened by the tumor, or bowing of the leg.
