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.
