17.1. PAPILLARY HYPERPLASIA
Papillary hyperplasia is a tumor-like lesion, possibly of viral or fungal (Candida) etiology, in the form of several small (up to 2-4 mm in diameter), painless, soft papillary outgrowths of bright red color on a wide base. Papillary hyperplasia is often localized to the hard palate in patients who use removable laminar dentures made of plastic in the upper jaw.
On microscopic examination, a thickening of epithelial folds with chronic inflammation is identified, but it is usually without keratinization.
Treatment of papillary hyperplasia starts with the manufacture of a prosthesis from other material or the use of a construction with the palate release. Discontinuation of wearing prosthesis leads to the relief of the inflammatory process and a decrease in growths in some patients; sometimes, papillary hyperplasia completely disappears. Surgical treatment with excision of growths followed by histological examination is performed on the patients, with dynamic monitoring in the absence of a positive result.
