Several histologic variants are reported, with myxoid, angiomatoid, giant cell, and inflammatory types most common in this location.
It was observed in the microscopic examination that the neoplastic tissue was composed of pleomorphic cells with ovoid-spindle shaped nuclei, pleomorphic polygonal cells with apparent nucleoli, and numerous multinuclear giant cells (Figure 1, part E).
About Giant Cell Tumor of Bone GCTB is a locally aggressive, benign tumor primarily afflicting younger adults between the ages 20 to 40.
The American College of Rheumatology 1990 criteria for the classification of giant cell arteritis.
No multinucleated osteoclast-type giant cells were present and no melanin pigment was seen on hematoxylin-eosin sections.
Since then, scientists have sought observations of such giant cells.
We prefer the phrase "temporal arteritis" to the phrase "giant cell arteritis" because giant cells are not seen in all TA patients having biopsies of the temporal arteries.
The pathologic examination of the surgical specimen from neck dissection shows numerous multinucle ated osteoclast-like giant cells within cellular and vascular stroma containing plump, oval mononuclear cells with nuclei similar to giant cells (Figure 3); expansile and infiltrative growth; frequent mitotic figures; secondary cystic degeneration, reactive bone formation; no cytologic atypia or pleomorphism.
These features are those of a fibro-osseous lesion with giant cells and were thought to be most in keeping with a central giant cell lesion, either a granuloma or a Brown tumour of hyperparathyroidism.

They are osteoclastomas that are very similar both radiologically and histologically to giant cell granulomas, which are lesions that occur almost exclusively in the jaws.
It is known as giant cell arteritis as giant cells form on the inside wall of the blood vessel in response to the inflammation.
Histologic findings on biopsy of the temporal artery can include mononuclear cell infiltration; granulomatous inflammation, usually with multinucleated giant cells, intimal proliferation, and vascular occlusion.
Findings may include a dense fibroblastic stroma, areas of cystic degeneration, osteoid, microfractures, haemorrhage, macrophages with hemosiderin, and multinucleated osteoclastic giant cells.
