A Rare Presentation of Non Ossifying Fibroma-A Case Report

Nonossifying fibroma is developed in children and adolescents and is usually asymptomatic. It typically arises in the metaphysis of long bone and rarely migrates toward the diaphysis with growth. Nonossifying fibroma is a benign fibroblastic lesion, which is also termed benign cortical defect and fibroxanthoma. A nonossifying fibroma rarely causes problems and does not interfere with healing or growth. The lesions are usually asymptomatic. With growth and remodeling of the bone, the lesion typically disappears and is replaced with normal bone. However, the lesion may weaken the involved bone, causing fracture. We report a very rare case of nonossifying fibroma involving diaphysis alone in a 10 year old girl with fracture at the site of lesion. Written, informed consent was obtained from the patient and her parents to publish this case report, including the images.
