Product definition of pleomorphic adenoma of minor salivary glands.
Thirteen cases of pleomorphic adenoma were studied by both immunohistochemical and other histochemical methods. The exocrine cells and myoepithelial cells appear to produce similar cell products as their normal salivary gland counterparts. Keratin was found in both exocrine cells and myoepithelial cells. CEA, secretory component, and lactoferrin were detected only in the tumor exocrine cells with adenoid differentiation. S-100 protein, ferritin, fibronectin, laminin and elastin were detected only in the myoepithelial cells. The residual sugars glucosyl, mannosyl, galactosyl and fucosyl were identified in both cell types, in variably detectable amounts.
