Bone tumours and tumour-like lesions can present a challenge for both radiographer and radiologist. NOF/fibroxanthoma is one of the more commonly seen bone lesions.

Nonossifying fibromas are made of fibrous tissue and are typically yellow or brown in color. They most often occur in the flared end of the lower femur (thighbone) and in the flared upper or lower ends of the tibia (shinbone). NOFs also sometimes occur in the fibula (the smaller bone in the lower leg) and in the humerus (upper arm bone).

Experts estimate 20 percent of people younger than 20 years old have at least one nonossifying fibroma. Other terms used include fibroxanthoma, benign fibrous histiocytoma, and non-osteogenic fibroma. What Are the Symptoms of Fibrous Cortical Defect? A fibrous cortical defect is a benign bone lesion that is often detected on radiologic or x-ray examination.

NOFs also sometimes occur in the fibula (the smaller bone in the lower leg) and in the humerus (upper arm bone). Atypical fibroxanthoma (AFX) is a dermal spindle-cell tumour that typically occurs on the head and neck of sun damaged older people. The tumour-like growth should be considered a type of skin cancer but it may behave in a benign fashion.

fibroxanthoma in Fig. 1, radiograph shows that entire circumference of this bone is enlarged by low-grade chondrosarcoma. Although large fibrous dysplasias can also enlarge entire circumference of bone, fibrous dysplasia will typically exhibit sclerotic rim with possible fibrous matrix mineralization. This

The author of this site prefes the name benign fibrous histiocytoma. Nonossifying fibromas are the most common benign bone lesions in children. Made up mainly of fibrous (scar) tissue, nonossifying fibromas are not aggressive. They can be thought of as ‘birthmarks’ in the bone, rather than true tumors. BFHs occur both in soft tissue and bone, with the majority of them affecting the skin of extremities in the early to middle adult life.[2,3] Moreover, BFH occurs in bones Developed by renowned radiologists in each specialty, STATdx provides comprehensive decision support you can rely on - Fibroxanthoma 2020-09-10 · Atypical fibroxanthoma lesions occasionally extend to the subcutaneous tissue. Note that atypical fibroxanthoma is a dermal-based process, while spindle cell squamous cell carcinoma variants (on the differential diagnosis) connect with the epidermis and show signs of keratinization.

Fibroxanthoma of bone is a confusing term that is sometimes used to encompass non-ossifying fibroma and fibrous cortical defect, and at other times synonymously with just non-ossifying fibromas. As non-ossifying fibroma and fibrous cortical defect are histologically the same, and differ only in size (non-ossifying fibroma >2-3 cm) it is safe to not lose too much sleep over this one. Fibroxanthoma (Nonossifying Fibroma) One of most common benign bone lesions of children and teenagers Metaphysis is most common location (may become metadiaphyseal with continued growth of child) Usually eccentric (or cortically based, appearing eccentric) Dense sclerotic border around lytic, sometimes bubbly, lesion Plasma cell granuloma (inflammatory pseudotumor) Plasma cell granuloma has also been called inflammatory myofibroblastic tumor, fibroxanthoma, histiocytoma, and fibrohistiocytoma.4 This lesion, which is seen frequently in adults, occurs rarely in children younger than … Out of a series of 900 biopsy-proven cases of skeletal "fibroxanthoma" (nonossifying fibroma, fibrous cortical defect), we studied 72 patients with more than one lesion.

They most often occur in the flared end of the lower femur (thighbone) and in the flared upper or lower ends of the tibia (shinbone).

Occasionally, very extensive tumors may require removal of the affected segment of bone and reconstruction of the joint.
