a Mononuclear spindle-shaped cells and pleomorphic giant cells (arrow) are immunoreactive for epithelial markers (CK8/18), while multinucleated osteoclast-like giant cells are negative (40x). b Mononuclear spindle-shaped cells and pleomorphic giant cells stain weakly for histiocytic marker CD68; in contrast, multinucleated osteoclast-like giant cells show an intense immunoreactivity for CD68 (arrow) (40x)
