Abstract
|
|
|
Giant cell tumor(GCT) occurs very unusually in the rib(less than 1% of GCT). We present the cytologic features of GCT of the rib. It showed multiple cellular clusters composed of characteristic. benign looking osteoclast-like
multinucleated
giant
cells and fibroblast-like mononuclear cells. The multinucleated giant cells contained numerous nuclei(average, 30 to 40 per cell, which were closely packed) . The nuclei in giant cells were remarkably uniform and round to oval. The
mononuclear.
neoplastic stromal cells were elongated and spindle-shaped.
There was no cytological malignant portion in the tumor.
