Nonossifying fibroma (fibrous cortical defect, fibroxanthoma) Nonossifying fibroma is a benign fibrous lesion of bone that appears as a well-defined lucent cortical lesion on x-ray. A very small nonossifying fibroma is called a fibrous cortical defect.

Nonossifying fibromas (NOFs) are the most common benign bone tumor in children. It is estimated that 30% to 40% of people under the age of 20 have an NOF, although few will have any symptoms. NOFs are often discovered by chance when a patient requires x-rays for another reason, such as a knee injury. 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.

In this study, SPECT/CT images revealed stress injuries in other sites than legs, systemic or locoregional pathologies in 12% of the patients (unilateral second metatarsal stress fracture in one patient, and unilateral knee fibroxanthoma in one patient in SF- group, calcaneocuboid stress fracture in one patient in SF+SS group).

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. 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.

However, they can cause problems because they may weaken bones, interfere with joint movement, or destroy nearby healthy tissue. Only a small percentage (5%) of patients with multiple skeletal fibroxanthomas had coexistent neurofibromatosis. These lesions are histologically indistinguishable from their solitary counterparts and most commonly present in the lower extremities. Four radiographic patterns were noted: (1) clustered lesions-usually about the knee.
