title: [Ultrastructure and clinicopathology of pleomorphic adenomas of the salivary gland. I. Methods and results].
abstract: The observations are a ultrastructural analysis of pleomorphic adenomas with one's own 14 cases. Pleomorphic adenoma is chief representative of the secretory tumour complex of salivary glands. Ultrastructure of three dominate secretory tumor cells and three nonsecretory celltypes are descripted. Ultramicroscopical differentiation of stroma elements an their transformations, henceforth regressive of tumour cells in the pleomorphic adenoma are discussed. The author give instructions for electromicroscopic diagnostic of this adenomas. Lastly there is tried to determine the "dignity" of pleomorphic adenomas by their ultrastructure for purpose of a adequate therapy.
