title: Papillary syringadenoma of the lower lip: report of a case.
abstract: A case of papillary syringadenoma that was located on the right side of the vermilion border of the lower lip in a 24-year-old man is described. The neoplastic epithelium showed two types of carbohydrate with variable topographical distribution and histochemical reaction. The cystic tumor areas showed subepithelial accumulations of mucopolysaccharides, probably related to topical collagen degradation.
