Abstract
Tissues from twenty-four patients with focal hyperplastic gingival lesions containing
calcification were stained for lysozyme (muramidase), alpha-1-antitrypsin, and alpha-1-antichymotrypsin.
In eighteen of the twenty-four cases the tissues stained positively for lysozyme,
and in all instances the tissues stained positively for alpha-1-antitrypsin and alpha-1-antichymotrypsin.
These data suggest that the fibrous components of these lesions are derived from tissue
histiocytes.
