[Clinicopathological analysis of 20 cases of giant cell granuloma of the jaw].

The pathological features of 20 cases of giant cell granuloma and 12 cases of giant cell tumor of the jaw were compared. Specimens of 8 cases of giant cell granuloma and 5 cases of giant cell tumor were stained with Wilder's reticular fiber stain and trichromic stain. The results showed that reticular fibers and collagenous fibers were more abundant and more focal in distribution in giant cell granulomas than in those of giant cell tumors. It is concluded that the two staining methods adopted are helpful in the differential diagnosis between these two kinds of diseases.
