Fibrous Cortical Defect and Non-Osteogenic Fibroma

Fibrous cortical defect and non-ossifying fibroma.

THE FIBROUS cortical defect and the non-ossifying fibroma are benign fibrous tumours occurring, in the cortex of the metaphysis, in the long bones of children and young adolescents. The fibrous cortical defect occurs in children usually under ten years of age; occasionally it develops into the more extensive lesion found in young adolescents and known as a non-ossifying fibroma. Despite the sup...

Non - Osteogenic Fibroma of Bone

attacks the efferent loop of jejunum was seen to enter the stomach. The patient underwent an immediate operation but no evidence of an intussusception was found. It had evidently undergone spontaneous reduction. Cases have been reported following partial gastrectomy as well as following gastro-enterostomy, Allen E. Grimes (I949) and W. L. McNamara (I944). They made the observation that there se...

Bone Production in Non-osteogenic Fibroma; an Attempt to Clarify Nomenclature in Fibrous Lesions of Bone.

The lesion in bone named non-osteogenic fibroma by Jaffe and Lichtenstein in 1942 and later-and more satisfactorily-renamed metaphysial fibrous defect by Hatcher in 1945, has been considered by various authors to be a benign tumour of bone (Jaffe and Lichtenstein I 942), the outcome of a circulatory disturbance (Hatcher 1945, Aegerter and Kirkpatrick 1958), a developmental defect (Cunningham an...

A Unique Adult-Type Distal Tibia Non-Ossifying Fibroma with Secondary Aneurysmal Bone Cysts Presenting with a Pathological Fracture

Various terms have been suggested to describe non-ossifying fibroma including fibrous cortical defect, cortical desmoid, metaphyseal fibrous defect and non-osteogenic fibroma. Regardless of the term used, they probable all refer to abnormal osteoclastogenesis at the metaphyseal region. Non-ossifying fibroma is a benign fibrogenic tumor primarily affecting children and adolescents. It is the mos...
