This book describes the most important lymphoproliferative and granulomatous disorders that may affect the oral and maxillofacial region. It discusses infectious, non-neoplastic and neoplastic conditions whose diagnoses are very challenging, given their extremely complex and heterogeneous characteristics. Written by worldwide experts in oral medicine, oral pathology and different medical specialties, the 46 chapters are richly illustrated by clinical, radiographic and microscopic images that comprise more than 1,000 illustrations. They are organized in the following sections: general overview and clinical presentation, microscopic findings, and immunohistochemistry and/or genetics. This work follows the current guidelines of the World Health Organization classifications and represents the first scientific resource dedicated exclusively to this topic, which will significantly contribute to improve diagnosticians' ability to recognize lymphoproliferative and granulomatous disorders in this clinical setting. Lymphoproliferative and Granulomatous Disorders of the Oral Cavity is aimed to health professionals from various specialties, including pathologists and clinicians, as well as dental and medical students.
