A Case Report of Osteoblastoma of Distal Femur: A Diagnostic Challenge

Le résumé fourni par la source

Osteoblastoma is uncommon benign bone tumor, representing approximately 1% of all primary bone tumor. The nidus of osteoblastoma is simulating to that of osteoid osteoma on histopathology and imaging, but it is larger in size. Osteoblastomas have a variable imaging appearance ranging from indolent to very aggressive, and many times difficult to differentiate from osteoid osteoma only based on imaging. A combination of thorough medical history, radiographic examination and clinical suspicion is at most important for differentiating osteoblastoma from osteoid osteoma. We present a case report of benign osteoblastoma of meta-diaphysis of distal femur in 15-year-old male child and histopathological confirmation.
