we have evaluated by means of immunocytochemistry the distribution of various cytoskeletal and contractile proteins ( cytokeratins , vimentin , desmin and alpha-smooth muscle actin ) in 23 salivary or lacrimal gland primary tumours ( 15 pleomorphic adenomas and 8 carcinomas in pleomorphic adenoma ) , one third of which contained areas of normal gland .
