The cell of origin and giant cell tumor remains unknown, but on the basis of most experimental evidence it is probably a mesenchymal cell showing some macrophage characteristics. The clinical features which have led people to suggest that this tumor may be a steroid receptor positive lesion are tenuous at best. Early histochemical data suggesting a presence of estrogen and progesterone receptors in giant cell tumor have not been substantiated by further studies. Immunohistochemical techniques have not identified estrogen receptors in giant cell tumor. Multiple biochemical techniques have failed to identify clinically significant levels of estrogen or progesterone receptors in giant cell tumor.
