Tumors Of The Odontogenic Apparatus And Jaws

Classifies and explains neoplasms and other tumours related to both the odontogenic apparatus and bone, epithelial cysts, and unclassified lesions.

This book describes the epidemiologic, radiologic, and histopathologic features of presently known neoplasms and hamartomatous or tumor-like lesions arising from the tooth-forming structures, as well as a number of distinctive jaw lesions that must be distinguished from odontogenic tumors.

Retaining the same scope as the first edition, this new edition deals with the classification and characteristics of tumours and tumour-like lesions. Similar information is also given on odontogenic and non-odontogenic cysts of the jaws. It is extensively illustrated with photomicrographs in colour, together with clinical radiographs and photographs of operation specimens to show the distinctive features of various lesions. The classification has been updated to reflect the present state of knowledge and changes in views, and includes a number of newly recognised entities.

The rare occurrence of tumors of the facial skeleton, whether of dental origin (odontogenic) or arising from bone (osteogenic), makes it impossible for a single observer to appreciate fully the epi demiologic and clinical behavior of these lesions, even if he controls the case material of a large institution. The systematic cooperation of many scientists is necessary in order to compile a meaningful body of information and make that information accessible for study. On the initiative of one of the authors (B.S.), the German-Austrian Swiss Association for the Study of Tumors of the Face and Jaws (DOSAK) resolved in 1971 to establish a special registry for tumors of the facial skeleton, including odontogenic lesions. This registry has been integrated into the bone tumor registry at the Swiss Asso ciation for Pathology in the Department of Pathology of the Uni versity of Basel. In 1974 DOSAK sponsored a symposium on odontogenic and os teogenic tumors of the jaws, at which illustrative cases were pre sented and discussed. These discussions revealed the problematic nature of these tumors and prompted a number of reclassifications, including some changes from benign to malignant and vice versa. It was found that radical and in some cases mutilating operations would not have been justified on the basis of the new classification. The discussions also underscored the importance of considering all factors - epidemiologic, clinical, radiologic and pathohistologi- when establishing a diagnosis.
