The aim of the study was to determine the distribution of histologically diagnosed nonodontogenic cysts nOCs over a year period in a Brazilian population. Biopsy records from patients with nOC from the files of the Oral Pathology Service during the period of — were evaluated. Among 10, oral biopsies, 58 met the criteria of nOCs. The most frequent nOCs were nasopalatine duct cysts Nasopalatine duct cysts showed predominance among females

There is evidence of cystic lesions in the jaws of humans and other animals in the distant past. Lesions of the jaws interpreted as cysts have been found in mummified specimens from the predynastic era c. Early descriptions of cystic lesions of the jaws were written by Aulus Cornelius Celsus early part of 1st century , Pierre Fauchard and John Hunter , among others. From about , papers on the nature and treatment of jaw cysts became more frequent.
Attempts to understand the relationship between various morphological types of cyst led to classifications such as Paul Broca's classification of odontomas which included odontogenic tumours, cysts and malformations. During the 20th century, a number of recognized treatises on cysts of the jaws were published, including the first three editions of the present book, and the first and second editions of Histologic Typing of Odontogenic Tumours issued by WHO, which included classification, definitions and histological descriptions of cysts of the jaws.
However, since no updated classification or monographs on jaw cysts have been published. For some years oral pathologists in particular have been looking forward to an updated book on the subject, so Foreword the appearance of the fourth edition of Professor Mervyn Shear's book on which Professor Paul Speight has become joint author is therefore highly appreciated.
The book will be of particular interest to postgraduates and specialists in oral and maxillofacial pathology, general pathologists, oral and maxillofacial surgeons and radiologists, and undergraduate students of dentistry.
Both authors have worldwide reputations and are highly esteemed oral pathologists. Professor Shear has for many years been one of the foremost experts on the subject. He has been a member of all three expert groups established by WHO to classify odontogenic tumours and cysts.
Professor J. Professor Speight is a diagnostic histopathologist with special expertise in odontogenic and bone tumours of the jaws, salivary gland tumours and mucosal pathology.
His main research interests are in the field of oral cancer with emphasis on mechanisms of infiltration and progression of oral carcinomas using, among other methods, immunocytochemistry, DNA transfection techniques, genetic markers and DNA ploidy analysis. If you are looking for a comprehensive, detailed and updated presentation of our knowledge in the field of cysts of the oral and maxillofacial regions you could not find a better book.
Finn Praetorius vi vii Preface to the Fourth EditionThere have been many changes to the fourth edition of this book, the first of which was published in , 30 years ago. The book has a new publisher, Blackwell Publishing, Oxford, who have taken over responsibility for the title from Wright and Butterworth Heinemann. The title of the book has been modified to 'Cysts of the Oral and Maxillofacial Regions', which reflects its scope more accurately.
The format of the book has changed and the clinical photographs and photomicrographs are now in colour. The text of this edition has been lengthened considerably in line with the proliferation of new publications in this field, particularly the odontogenic keratocyst.
This will be reflected in the current list of references, which has increased significantly. We have tried to keep this text as up-to-date as possible by including articles that have appeared well into We have however, omitted the chapters on 'history' and on 'treatment'. The latter chapter by Professor Gordon Seward was well-received by reviewers of the 3rd edition, but the authors and publishers felt that this topic was now very well covered in specialist publications on oral surgery.
We have instead added paragraphs on general principles of treatment at the end of each of the chapters. As in the past, we have attempted to produce a text that will be useful to a range of professionals and also to undergraduate and postgraduate students as well as anyone doing research in this field. The clinical features, radiology, pathogenesis and histopathology of each of the cysts, are set out at the beginning of each chapter, and we believe that undergraduate and postgraduate students will find these useful in their studies and in their preparation for examinations.
His contributions to oral pathology, particularly in human genetics, have been extraordinary. In the field of jaw cysts, his name is linked to the calcifying odontogenic cyst, eponymously known as the Gorlin cyst; for his work associating the odontogenic keratocyst with the naevoid basal cell carcinoma syndrome, often referred to as the Gorlin syndrome; and for his studies on the genetics of the syndrome.
Over the past 8 years since publication of the second edition of this book, the subject of jaw cysts and cysts of the soft tissues in and around the mouth has continued to evoke considerable interest among clinicians, pathologists and basic scientists, and numerous papers have been published on these topics.
Advances in immunocytochemistry have provided the opportunity for studies on the epithelium of cyst linings in an attempt to clarify the pathogenesis of the many varieties and to improve the accuracy of microscopic diagnosis; while further immunological investigations have been undertaken to identify the changes which initiate the formation of radicular cysts in periapical granulomas, and into other aspects of cyst pathology.
Basic research has also led to progress in the understanding of the mechanisms involved in the enlargement of cysts. A few new entities have been identified such as the mandibular infected buccal cyst, the glandular odontogenic cyst and AIDS-related bilateral lymphoepithelial cysts of the parotid glands; while our understanding of lesions such as the unicystic ameloblastoma, the botryoid odontogenic cyst and the postoperative maxillary cyst has been enhanced by careful clinicopathological research.
In order to do justice to all this recent work and to bring it to the attention of others in the field, I have added references to about new papers. In preparing the book I have tried to make the work useful to undergraduate and postgraduate students, dentists, oral and general surgeons, radiologists, oral and general pathologists, and anyone doing research in the field.
I trust that readers will not find it difficult to gain access to the information they seek. In consultation with the publishers, Butterworth-Heinemann, it was decided to take the book out of the Dental Practitioner Handbook series, and to produce it in a new format. We have also invited the collaboration of Professor Gordon Seward, who kindly agreed to write a chapter on the treatment of cysts.
His expert input will undoubtedly enhance the value of the book to those who treat these lesions. As with past editions, I have received invaluable assistance from a number of people. I am greatly indebted to Professor Mario Altini, Head of the Department of Oral Pathology of the University of the Witwatersrand, for allowing me access to the material in the department, and to him and other members of his staff who were generous in assisting me with the preparation of material.
Many other colleagues were also extremely kind in lending me good sections and good illustrations, and these have been acknowledged in the text. Johannesburg Preface to the Third Edition viii Preface to the Second EditionIn the period since the first edition of this book, there have been many publications in the field.
This has given me the opportunity of doing an extensive revision of the text by introducing the newer concepts and reassessing the older. Some references have been added, not all of them published since the first edition. The numbers of jaw cysts from my own department which have been used in this edition, particularly for the clinical analyses, have been increased from to Most of the diagrams have therefore been redrawn and the tables revised to include the new data.
These additional cases were extracted from the departmental archives by Dr A. Rudick in preparation for his research dissertation leading to the degree of MSc Dent , and it is a pleasure to acknowledge his contribution in this regard. The classification used in the first edition has been modified slightly as a result of my experience using it in teaching undergraduate and postgraduate students.
The number of figures used has been increased by 24 and many of the original illustrations have been replaced. Colleagues have been most generous in allowing me to Caroline Connolly was the Commissioning Editor for Blackwell Publishing, Oxford, who took us through the discussions leading to the offer of a contract to publish the book.
Her negotiating skills and sensitivity to the wishes of the authors as well as the requirements of the publishers were greatly appreciated. After her transfer to another position, her place was taken by Katrina Chandler, who has seen us through to publication. Our main contact with the publisher has been Amy Brown, senior editorial assistant, who has provided invaluable support, guidance and advice in the preparation of the manuscript and the accompanying illustrations.
We are greatly indebted to her. Kate Gardner, the Production Editor, and Mirjana Misina, were responsible for all aspects of production of the book: copy editing, typesetting, proof reading and dealing with all the artwork.
The authors are indebted to them for their meticulous attention to detail. An academic work of this kind is dependent on a close and harmonious relationship between authors and production staff, and it is a pleasure to recognise the partnership that we have enjoyed. Our respected colleague and friend, Dr Finn Praetorius, very kindly agreed to write a foreword to the book and we are immensely grateful to him for doing so.
Professor Mario Altini, head of the Department of Oral Pathology in the University of the Witwatersrand, Johannesburg, has been supportive and encouraging, and has generously provided the authors with updated data on the material accessioned in his department since the previous edition in We should like to thank both of them for their contribution to this edition. Our colleagues in the Department of Oral Pathology, University of Sheffield have been very helpful in allowing us access to their files and photographs, especially Professor Chris Franklin and Dr Adam Jones who have provided data from their analyses of lesion incidence and Dr Geoffrey Craig for useful discussions on the paradental cysts and for giving free access to his archival material.
Other colleagues have responded generously to requests for use of clinical photographs and radiographs, and they have been acknowledged by name in the legends to the relevant figures. We very much appreciate their kind contributions.
Professor Finn Praetorius of the University of Copenhagen has been extremely obliging in discussions with him on the classification of odontogenic ghost cell lesions, a very complex and controversial subject, and we acknowledge with gratitude his generosity in allowing us to use his most recent classification of this group, as illustrated in Table 8.
Is it a benign neoplasm? Kramer has defined a cyst as 'a pathological cavity having fluid, semifluid or gaseous contents and which is not created by the accumulation of pus'. Most cysts, but not all, are lined by epithelium. Cysts of the oral and maxillofacial tissues that are not lined by epithelium are the mucous extravasation cyst of the salivary glands, the aneurysmal bone cyst and the solitary bone cyst. Despite these examples, most pathologists prefer to describe those pathological cavities not lined by epithelium as 'pseudocysts'.
Reichart and Philipsen prefer to describe these as 'cavities' rather than cysts; hence, for example, 'aneurysmal bone cavity'. The classification proposed in this book divides the cysts of the oral regions into those lined by epithelium, and those that are not. Epitheliallined cystic odontogenic neoplasms, such as the unicystic ameloblastoma, are not included in this edition. Cysts historically named globulomaxillary, median palatine and median mandibular cysts have been convincingly shown by numbers of studies to be other odontogenic or developmental cysts.
This terminology is no longer used in diagnostic oral pathology departments in most parts of the world and the authors of this edition have decided to exclude it from the classification. This is a classification of jaw cysts, not the classification.
Many other classifications have been published and may well be perfectly satisfactory and readers are encouraged to use any classification they find valuable as an aid to memory and understanding. In this edition of the book, the cysts are classified under three main headings: I Cysts of the jaws II Cysts associated with the maxillary antrum III Cysts of the soft tissues of the mouth, face, neck and salivary glandsThe cysts of the jaws are divided into those that are:A Epithelial lined B Not epithelial linedThe epithelial-lined cysts may be either of: Frequency of cysts of the oral regionsFrequency statistics differ from incidence studies in that they are not standardised against known population data, such as age, gender and ethnicity.
For data to be comparable between populations and internationally, age standardised incidence rates per for each lesion, compared with a standard world population, are a requirement for all national cancer registries. Age-standardised incidence rates for odontogenic keratocysts and for dentigerous cysts in a defined area the Witwatersrand of South Africa have been reported by Shear and Singh and Rachanis and Shear The resulting data for these two cysts are discussed in the relevant chapters.
Frequency studies, based either on hospital or on departmental archival records, are the method used most often in clinical investigations. These may have been based on very few cases, particularly in rare conditions, or large numbers of cases in departments with considerable patient turnover recorded over many years. While these provide useful data on the behaviour and treatment of different diseases, they are of limited use in international comparative studies.

The aim of this study is to review cysts of the oro-facial region seen at a tertiary health centre in Ibadan and to categorize these cases based on Lucas, Killey and Kay and WHO classifications. Materials and Methods: All histologically diagnosed oro-facial cysts were retrieved from the oral pathology archives. Information concerning cyst type, topography, age at time of diagnosis and gender of patients was gathered. Data obtained was analyzed with the SPSS
Radicular cyst is believed to be derived from the epithelial cell rests of Malassez. The associated tooth is nonvital, usually asymptomatic, and may result in swelling, tenderness, tooth mobility, or other problems with rare possibility of neoplastic transformation of its epithelial lining.

A cyst is a pathological epithelial lined cavity that fills with fluid or soft material and usually grows from internal pressure generated by fluid being drawn into the cavity from osmosis hydrostatic pressure. The bones of the jaws, the mandible and maxilla , are the bones with the highest prevalence of cysts in the human body. This is due to the abundant amount of epithelial remnants that can be left in the bones of the jaws. The enamel of teeth is formed from ectoderm the precursor germ layer to skin and mucosa , and so remnants of epithelium can be left in the bone during odontogenesis tooth development. The bones of the jaws develop from embryologic processes which fuse together, and ectodermal tissue may be trapped along the lines of this fusion.
