Histological Typing of Salivary Gland Tumours (Who. World Health Organization. International Histological Classification of Tumours) Gerhard Seifert 2nd edition

This second edition is more extensive and detailed than the previous one - now a reference of two decades standing. New technical methods have increased our understanding of many tumours, and the earlier group of monomorphic adenomas has been separated for easier identification, while clearly defined tumours - even if uncommon - have their own category. With reference to their differences in prognosis and treatment, the various types of carcinomas are now listed separately, and new entities have been adopted. The inclusion of the TNM classification of salivary gland tumours together with the more detailed description of the tumour-like lesions will contribute to an even better understanding.
