Is fibrous cortical defect cancerous?
Fibrous cortical defects (FCD) are benign bony lesions and are a type of fibroxanthoma, histologically identical to the larger non-ossifying fibroma (NOF).
What does cortical deformity mean?
n. A common small defect of a bone, in which the cortex is filled with fibrous tissue, occurring most frequently in the lower femoral shaft of a child. nonosteogenic fibroma.
What is non-ossifying fibroma?
A non-ossifying fibroma is a benign (non-cancerous), non-aggressive tumor that consists mainly of fibrous tissue. It usually occurs in the thighbone or shinbone but may also occur in the upper extremities. A non-ossifying fibroma usually produces no symptoms. It usually resolves by itself. It never spreads.
Is fibrous cortical defect painful?
The fibrous cortical defect is seen as a small radiolucent defect in the metaphyseal cortex, in close proximity to the growth plate. They have asymptomatic, self-limited natural history. Lesions may be asymptomatic. However, as they grow, they may become painful or undergo pathologic fracture.
What does cortical bone do?
Cortical bone is the dense outer surface of bone that forms a protective layer around the internal cavity. This type of bone also known as compact bone makes up nearly 80% of skeletal mass and is imperative to body structure and weight bearing because of its high resistance to bending and torsion.
What is fibrous cortical defect?
Category: Bone and Joint. To begin with, the fibrous cortical defect is a benign fibrous tumour occurring, in the cortex of the metaphysis, only in the long bones of children and young adolescents. The term “fibrous cortical defects” has been given, as these lesions are composed of fibrous tissue.
What is a fibroma on the bone?
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.
