[Some problems of clinical characteristics, diagnostics and treatment of pleomorphic adenoma of salivary glands].

The author evaluates the clinical characteristics in the light of the concepts proceeding from the International histological classification of tumours of the salivary glands on the base of his own experience in the treatment of 208 patients with pleomorphic adenoma of the salivary glands. The existing hospital documentation of the treated patients was analyzed as well as a repeated evaluation of the histological diagnosis made during the treatment and control of the therapeutic results via periodical inquiry of the treated patients. The author confirms the ratified unified nomenclature of the International classification and the benign nature of the pleomorphic adenoma. In that aspect he defends the surgical treatment of the pleomorphic adenoma as the method of choice and the high diagnostic value of the urgent intraoperative histological study. He advances the thesis for the application of more radical methods in the surgical treatment of recurrent pleomorphic adenoma of the parotid gland. According to the author, the morphological characteristics of the pleomorphic adenoma have no effect on the choice of the surgical methods for the treatment of that tumour.
