Juvenile ossifying fibroma (JOF) is an uncommon fibro-osseous lesion occurring in the facial bones. It has been recognised as a separate histopathological entity among the fibro-osseous group of lesions. Fibro-osseous lesions of the craniofacial bones are difficult to classify and treat however a common factor to all is the conversion of the bone to benign fibrous tissue with a varying degree of mineralised tissue. This case describes a 15 year old patient with a juvenile aggressive ossifying fibroma (JAOF) and an estimate of the rate of growth of such a rare lesion.

Common Benign Bone Lesions and Return to Sports: A Case Report and Scoping Review.
Am J Sports Med
January 2025
University of Alabama at Birmingham, Birmingham, Alabama, USA.
Background: Benign bone lesions are a common incidental finding in athletes during workup for musculoskeletal complaints, and athletes are frequently advised to halt participation in contact sports. There are no current guidelines to assist clinicians in referring patients with these lesions to a subspecialist or in advising athletes on the safety of returning to sport.
Purpose: To assist sports medicine physicians in appropriate referral for patients with benign bone lesions through presentation of a literature review and the case of an adolescent athlete with a benign bone lesion in a location with a significant fracture risk.
Interaction Between Sclerostin and Mast Cells in Fibro-Osseous Lesions of the Jaws.

Department of Dentistry, Federal University of Santa Catarina, Florianópolis, Santa Catarina, Brazil.
Objective: To assess the sclerostin, β-catenin, and tryptase expression in fibro-osseous lesions (FOL) of the jaws.
Subjects And Methods: Immunohistochemistry analysis was performed for these proteins on FOL and non-lesional bone. The sclerostin-positive cells were scored from 0 (no expression) to 3 (high expression).
Fibro-osseous lesions of the sinonasal tract: a contemporary review.
Curr Opin Otolaryngol Head Neck Surg
February 2025
Department of Otolaryngology - Head & Neck Surgery, University of Florida, Gainesville, Florida, USA.
Purpose Of Review: Fibro-osseous lesions (FOL) are benign, slow-growing lesions that are often incidentally discovered in the sinonasal cavity. They may necessitate surgical resection in patients with postobstructive sinusitis, or in cases of cranial nerve and orbital compression. We examine the recent advancements in otolaryngology relating to diagnostic characteristics and treatments for FOL, with emphasis on new technologies to improve outcomes and reduce recurrence.

Nasal and paranasal sinus masses can arise from a wide range of conditions, both benign and malignant, as well as congenital or acquired. Diagnosing these masses is often challenging, requiring a combination of nasal endoscopy, imaging studies, and histopathological analysis. Initial imaging frequently involves computed tomography or cone beam computed tomography (CBCT) to evaluate the bony anatomy of the nasal cavity and surrounding sinuses, while magnetic resonance imaging (MRI) is typically used for detailed assessment of soft tissues and to aid in differential diagnosis when the findings are inconclusive.

Non-ossifying fibroma (NOF) is a benign expansive lytic lesion more frequently found in children and adolescents at the metaphysis of long bones in and around the knee joint, typically resolving spontaneously or by ossification. This report presents a rare case of an 11-year-old child with a pathological subtrochanteric femur fracture attributed to an underlying NOF. We describe the diagnosis and surgical management of curettage and internal fixation using a proximal humerus locking plate, resulting in complete resorption of the lytic zone and an excellent clinical outcome.
