[The demonstration of a system of elastic fibers in a study of fibromatous lesions of the oral mucosa].
The elastic fibers system, as visualised by orcein after potassium peroxymonosulfate oxidation in fibromatous lesions of the oral mucosa, is generally sparse. Rich orcein + fibers network was observed in only 5 of our 20 cases of reactive fibromas. Orcein + fibers are absent in the inflammatory areas. These observations rise the problem of the elastogenesis by the fibroblast in healing and neoplasia, and confirm the role played by the proteolytic enzymes during inflammation.
