On a variant of giant cell tumor

Abstract

We had oppotunity to study so called a giant cell tumor variant recently. A 12-year-old girl was first visited to our clinic in June, 1971. Pain and swelling had developed in upper part of right tibia. Roentgenogram showed a round, limited area and a vague, fuzzy mottled appearance. Microscopic examination revealed a composed findings of giant cells, variable size cells (round, oval or polyhedral), osteoid matrix and chondroid matrix in this material.
It was beleaved that it was a benign chondro-blastoma rather than a genuine giant cell tumor.
