This book is divided into 3 main sections: cysts and odontogenic tumors (lesions related to the dentition); fibro-osseous lesions and giant cell lesions, which are unique to the maxillofacial skeleton; and bone lesions, which also occur in other parts of the body. Individual diseases are described with a special emphasis on histomorphological aspects. Some lesions may pose considerable diagnostic problems due to shared microscopical features and the authors' aim is to provide reliable diagnostic guidelines for the surgical pathologist who has to deal with specimens from this area. The majority of the currently available textbooks on head and neck pathology are mainly devoted to soft tissue lesions, paying less attention to the pathology of the diseases that involve the hard tissues. Texts on general skeletal pathology cannot address this gap, as the maxillofacial skeleton differs from the bones elsewhere in the body in several respects. Therefore, the book discusses both bone disorders that are restricted to the head and neck, and diseases that also occur in the extragnathic skeleton.
