Introduction: Benign bone tumour arising from fibroblasts. Usually seen in the metaphyseal region of immature skeleton and most of the times it is asymptomatic. It may be an incidental finding in a x-ray taken for some other purpose or bigger lesions may present as pathological fractures. They have a characteristic radiological appearance of serpigenous margins which have pencil lined sclerotic borders.

Incidence: not uncommon Differential Diagnosis: none Prevention: nil

Treatment: Big lesions are curetted prophylactically to prevent pathological fractures and bone grafted. Once they present with a pathological fracture - either they are immobilized in plaster cast till the fracture unites and then curetted and bone grafted or the fracture is openly reduced and internallyfixed and at the same time the lesion is curetted and bone grafted.
