My aim was not only to give information illustrated with pictures, but also to make this book suggest and spread the importance of the cooperation between various fields of medicine. The best results may be expected only if dentists and physicians consider the mucous membrane of the mouth a "mini display" of diseases of the internal organs, where signs and symptoms of the body's pathological processes are presented. Thus the proper diagnosis and treatment of diseases of the skin and the oral mucosa are only possible with being acquainted with internal and systemic diseases and taking them into consideration. In this new, expanded and revised edition of the book I intended to further augment the number of color pictures (1827 photos) besides presenting diseases worth highlighting from my 35 years of clinical practice.
In an international comparison, the frequency and mortality rate of oral oncological diseases have increased dramatically in Hungary in the recent decades. During the expansion and revision of the book, I wanted to put special emphasis on providing support primarily in stomatologic tumor diagnostics and oncotherapy to help control the above-mentioned unfavorable tendency.
The teaching of foreign students and the presentation and treatment of tourists as patients urged me accomplish the book by including diseases occurring in geographically remote countries, and not or barely known in Hungary, to further extend our knowledge.
The pictures presented in the atlas were selected from photos taken of patients registered and treated at the Outpatient Department of Oral Oncology and Oral Medicine at the Faculty of Dentistry and Oral Surgery in Szeged since 1970.
As compared to the atlas published in 1992 (in Hungarian), the new monographic book is different, and hopefully offers more in that it provides help not only in oral and maxillofacial diagnostics, but also in therapy.
I took the clinical picture as a basis for diagnosing diseases; however, the final diagnosis was achieved by clinicopathologic studies (histology, electromicroscopy, immunohistology, microbiology, etc.).
I hope that this new edition reflects my experience in Oral and Maxillofacial Medicine, an experience that has "matured" for several decades; and hope that dental and medical practitioners and clinicians will benefit from this knowledge and use it for the better treatment and care of patients.
I also hope that this book will be able to provide useful supplementation for various specializations (otorhinolaryngology, dermatology, internal medicine, oral surgery, pediatrics, oncology, etc.) as well. In my opinion, this book may offer additional support for graduate and postgraduate education, and may be of interest among general practitioners, too.
I would like to believe that this handbook will not only work its way into Hungarian dental and medical practice, but will also take part in helping graduate and postgraduate education beyond the borders of the country.

I owe Katalin Susula Gazdagné thanks for typing the text and putting it into the computer. Terézia Henel, Csilla Gyöngyösi Enginé and Henrietta Guti assisted me in properly registering the patients. The photos were taken by László Vígh, Zsuzsanna Kiss-Dózsai Molnárné and István Sonkodi, and I am grateful to Mihály Dezső for scanning the pictures. Dr. Géza Regdon and Dr. László Módné helped me in writing the chapter on therapy. Katalin Márton and Mária Kocsó Hollcsikné were also of assistance to me.
It was an exceptional pleasure and privilege for me that Professor Jolán Bánóczy and Professor István Gera, who are recognized authorities in Hungary and also internationally, assisted me as consultant editors, and that I was able to rely on their professional advice.
Thanks are due to dr. Ágnes Baunok, dr. Zsuzsanna Jónás, dr. Csilla Keresztes, dr. Balázs Marton and dr. Gábor Marton for translating the Hungarian version of the book into English.
Finally, I would like to thank the staff of Semmelweis Publisher, and director László Táncos, for the beautiful and high-standard publication of the book.
