The borders are well defined and usually not sclerotic. Pathologic fracture is present in 5-10% of giant cell tumours. Dynamic MRI shows a fast uptake and a slow wash out of contrast. Atlas Genet Cytogenet Oncol Haematol. 2003; 7(3) 194 Bone: Giant cell tumour Forsyth RG, Hogendoorn PCW Alias Pathology Osteoclastoma; Giant cell tumour of bone A mixture of four components can be distinguished: - spindled-shaped and rounded mononuclear cells, Clinics and pathology - osteoclastic-type giant cells and small blood vessels. Disease The spindle-shaped mononuclear cells are regarded as neoplastic on results from electron microscopy and cell Locally destructive, benign and mono-ostotic tumoral cultures. The origin of this cell type is still unknown, lesion, typically presenting in the meta-epiphysis of but it is thought to arise from the primitive long tubular bones with predilection for the knee region mesenchymal stromal cell.

Poly-ostotic lesions are forms or strong nuclear atypia is noted, a secondary exceptionally rare, counting for less than 1% of all sarcomatous malignancy is almost always present. cases. In these cases especially brown tumour of Secondary changes may be present like osteoid hyperpara-thyreoidism should be considered, which deposits, foci of fibrosis, collections of foamy cells or may look histologically identical.

Mostly this is vascular invasion and pulmonary metastases (1%) may restricted to younger patients (median of 14 years) and occur. low histological grade giant cell tumours. Phenotype / cell stem origin As mentioned earlier, this tumour can histological be graded into 3 grades according to Jaffe (1940) or into 4 Not yet determined. grades (Netherlands Committee on Bone Tumours). Embryonic origin According to the latter grading system, grade 1 en 2 are Mesoderm. considered as being benign, grade 3 as borderline malignant and grade 4 as malignant tumours. Grade 4 Etiology tumours show histological overlap with malignant The exact origin is still unknown, but data obtained fibrous hystiocytoma of bone. Although many authors from ultrastructural analyses and cell cultures, suggest are sceptic about grading giant cell tumours, this shows that the "stromal" cell, or mononuclear spindle cell, is a good correlation with clinical outcome. neoplastic. The mononuclear rounded cells and the In that time no adjuvant chirurgical treatment, like osteoclastic giant cells are seen as reactive. Therefore, cryosurgery or phenol additive was used. Now-adays some suggest that "stromal cell tumour" is a better the usefulness of grading in relation to recurrences is name, because this fits more precisely the concept of highly influenced by more effective surgical adjuvant the mononuclear spindled cell (stromal cell) as techniques. According to literature still 20% of the neoplastic. giant cell tumours will recur, despite of these new Epidemiology surgical techniques. Together with the risk of developing pulmonal metastases, grading of giant cell This tumour represents 8% of all primary and tumours is in our view still valuable. In this grading approximately 20% of benign primary bone tumours. system mitosis, pleiomorphism of the spindled Mostly affecting adults in the third, fourth and fifth mononuclear cells, giant cells and the individual size of decade of life (72%).

A pathological grade 3: 5%, grade 4: 3%). fracture could occasionally be the first sign of this tumour. Atlas Genet Cytogenet Oncol Haematol. 2003; 7(3) 195 Bone: Giant cell tumour Forsyth RG, Hogendoorn PCW Mixture of three cellular components composites the tumour: tumoral spindle shaped mononuclear cells, reactive rounded mononuclear cells and diffusely scattered osteoclast type giant cells. Note that mitoses are strictly limited to the first cell type. Table : Grading of giant cell tumours according to the Netherlands Committee on Bone Tumors. Treatment surgical technique and expertise in combination with the histological grade of this tumour. Although Surgical intervention is the only treatment of choice. pulmonary metastases may occur in rare cases, Mostly a curettage followed by local adjuvant angiovascular invasion does not have any significant cryosurgery or phenol instillation is sufficient to influence on its prognosis.
