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.

Aims: Ossifying fibromyxoid tumour is a rare mesenchymal neoplasm predominantly affecting adults characterised by a multinodular growth pattern and the presence of a fibrous pseudocapsule with areas of ossification. Prompted by the recognition of a non-ossifying ossifying fibromyxoid tumour with lipomatous differentiation which caused diagnostic difficulty, we sought to further explore cases of ossifying fibromyxoid tumour with non-osseous heterologous elements.
Methods And Results: A search of our institutional and consultation archives revealed three additional cases that demonstrated lipomatous components and two cases with cartilaginous differentiation.

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.

Fibrous cortical defect (FCD) and non-ossifying fibroma (NOF) are incidentally recognised and benign developmental lesions. The objective of this study was to ascertain the clinical manifestations and symptoms of FCDs/NOFs in children and adolescent patients, to characterise the lesions radiologically using X-ray and MRI techniques, and to determine the relationship between physical activity and the condition. The study included patients under the age of 18 with radiological lesions on their extremities.

Objective: First, to determine the frequency and spectrum of osteoid osteoma (OO)-mimicking lesions among presumed OO referred for radiofrequency ablation (RFA). Second, to compare patient sex and age, lesion location, and rates of primary treatment failure for OO based on histopathology results.
Materials And Methods: A retrospective review was performed of all first-time combined CT-guided biopsy/RFA for presumed OO at a single academic center between January 1990 and August 2023.
