however, in addition, the end of each chapter now contains self‐ assessment multiple‐choice questions with feedback comments on the correct answer and distractors The revisions of Chapter 1 notably include a number of newly marketed diagnostic adjunctive devices and methods Chapter 3 provides updated information on some of its pathologic conditions, particularly the nature of hemangiomas versus vascular malformations and the increasing clinical impact the human papillomavirus type 16 has on malignant transformation (i.e squamous cell carcinoma) of specialized oropharyngeal epithelium as opposed to the oral cavity proper Chapter 5 introduces the term “oral potentially malignant disorders” and initial commercial products designed to add additional information to their predicted clinical behavior and management Appendix B has been extensively updated to reflect the ever‐changing drug formulary available to the clinician to treat oral soft tissue diseases Lastly, some of the photographic images have been added or updated to enhance a lesion’s features We hope our efforts have enhanced the utility of this textbook for your chairside evaluation, differential diagnosis formulation, establishment of provisional and final diagnosis, and management of your patient’s diagnosed oral mucosal diseases Michael A Kahn J Michael Hall vii Preface to the First Edition This textbook is intended to be a practical guide and reference source for the basic clinical aspects of soft tissue oral and maxillofacial disease It is not intended to be an all‐encompassing tome of oral pathology but rather to include those aspects of this dental specialty that are its most important foundational information and the most frequently encountered orofacial soft tissue diseases The book is intended for health‐care practitioners whose occupation involves encountering a variety of conditions and diseases of the oral cavity and its contiguous anatomic structures; it is not intended to be a reference source for oral medicine (i.e details of the medical aspects of a particular disease within the oral cavity) We envision this book not as one to reside on a clinician’s library shelf gathering dust and rarely referred to, but rather one used regularly within the dental operatory to help the clinician’s decision making: that is, deciding what is the best thing to for the patient when a pathologic condition is initially discovered, how to determine its most likely provisional diagnosis or differential diagnosis, whether to biopsy or refer for consultation by a dental or medical specialist, and how to most accurately and effectively communicate that information to the patient so the patient can give informed consent about his or her treatment course and management Since 1984, when we began our residency training in oral pathology at Emory University’s School of Dentistry (Atlanta, GA), we have increasingly recognized specific essentials of oral pathology that need to be learned, understood, and used by all dentists; furthermore, we have witnessed common diagnostic pitfalls and management mistakes This book is the culmination of our cumulative and collective experiential wisdom gained during our training as well as our subsequent years of being in teaching institutions By interacting with dentists, with dental and dental hygiene students, and with physicians and patients in clinical and educational settings as well as by participation in active oral pathology biopsy services and clinical consultation clinics, we have become aware of the lesions commonly encountered but misunderstood by them or unknown to them Michael A Kahn J Michael Hall ix Acknowledgments We are deeply indebted to the team at Wiley Blackwell who initiated contact with us to consider this endeavor: to Ms Shelby Allen and Rick Blanchette, whose vision and interest in our continuing education materials sparked an interest to share its content with a wider audience of dental practitioners and whose shepherding of the first edition resulted in its enthusiastic use and opportunity to create a second edition For this second edition we give thanks to the guidance of Ms Erica Judisch (Executive Editor, Veterinary Medicine and Dentistry), Ms. Anupama Sreekanth (Project Editor), Ms Susan Engelken for cover design, and Ms Natasha Wu (Assistant Production Editor) At the American Dental Association (ADA), we thank Dr Pamela Porembski (DDS, Senior Manager, Council on Dental Practice), Carolyn Tatar (Senior Manager, Product Development), and Dr Kathleen O’Laughlin (DMD, Executive Director) for their belief in this initial endeavor, supplying support and assistance and working with many other members of the ADA to gain the project’s acceptance and affiliation We also thank our colleagues at the various institutions we have worked at, as they have shared their knowledge and teaching materials with us In particular, Drs Robert Goode, Lynn Solomon, and Eleni Gagari were involved in many of the materials used in constructing the content of Chapter 7 In addition, we are very grateful to our colleagues throughout the world who have shared their unrestricted‐use clinical images with us at regional and national oral pathology meetings We thank Ms Heidi Price for creating the original line drawings of Chapters and Last, we thank our many patients and their clinicians who shared their patients and/or their biopsied tissue with us and our students, whose pathology questions spurred us to either respond from memory or seek additional references in order to answer M.A.K J.M.H xi Section I Detection and Documentation The Extraoral and Intraoral Soft Tissue Head and Neck Screening Examination It is paramount that the dental clinician establishes a repeatable, logical, s equentially organized, and systematic approach to screening the soft tissues of the head and neck region It should be understood that this is not an “oral cancer s creening,” since all abnormal conditions should be detected Performing an oral cancer screening means looking for a single condition, cancer, at a single point in time; the dental clinician performs a complete exam, looking for all soft tissue abnormalities at a single point in time There is no universally acknowledged step‐by‐step approach; therefore, the following is the one we adhere to and it can be modified as desired The important point is that, whatever sequence is established, it should be strictly adhered to each time to ensure that no step is omitted A suggested ideal sequence of steps for a complete oral mucosal screening procedure of a new patient includes the following: • • • • • • • • Introduction to the patient Patient’s chief complaint History of the present illness Medical (including social) and dental histories Physical examination (to detect the site, morphology, and color of abnormalities) Review of data and formulation of a clinical differential diagnosis Additional clinical and laboratory tests ordered, as indicated Final definitive diagnosis with a treatment/management plan formulated Certainly, the clinician should establish a pleasant rapport with the patient so that excellent communication and trust are established Often, the most critical or important piece of information a patient possesses does not get transmitted to The ADA Practical Guide to Soft Tissue Oral Disease, Second Edition Michael A Kahn and J Michael Hall © 2018 by the American Dental Association Published 2018 by John Wiley & Sons, Inc Common Oral Soft Tissue Lesions 99 (a) (b) (c) Figure 3.75 (a) Traumatic (irritation) fibroma of the buccal mucosa secondary to accidental biting (b) Traumatic fibroma of the tip of the tongue secondary to biting (c) Traumatic fibroma slightly inferior to the right occlusal plane of the buccal mucosa 100 Diagnosis and Management (a) (b) (c) Figure 3.76 (a) Large, firm swelling of mucoepidermoid carcinoma of the buccal mucosa (b) Large, unilateral, firm, and slightly tender posterior swelling of the hard palate near the junction with the soft palate diagnosed as adenoid cystic carcinoma (c) Firm, mobile submucosal swelling of the upper lip’s midline diagnosed as monomorphic adenoma (canalicular adenoma) Common Oral Soft Tissue Lesions 101 • Treatment – Complete excision with conservative normal tissue margin for benign tumors and wider excision for malignant lesions Sialolith, minor and major salivary glands (Fig. 3.77a,b,c) • Site – Floor of the mouth (submandibular gland – Wharton’s duct > sublingual gland); upper lip and buccal mucosa (parotid gland – Stensen’s duct) • Morphology – Small hard submucosal mass; sometimes palpable • Color – Pink to yellow white • Signs and symptoms – Calcium salt deposition with nidus of debris, bacteria, and so on Sialolith is usually painless but the patient can have sensation of fullness or tenderness, especially prior to eating (i.e episodic); severity of swelling and/or pain depends on degree of obstruction Secondary ascending acute sialadenitis may occur Radiopaque mass is seen on radiographic image • Treatment – Removal of the large stone by surgery; if small, sometimes it can be “milked” to extrude it through the duct’s orifice Lithotripsy has also been effective Parulis (gum boil, abscess) (Fig. 3.78) • Site – At the terminus of a fistula that has perforated, the cortical bone in the area of a nonvital tooth; facial usually, or lingual or palatal gingiva/alveolar mucosa is the most common site; also vestibule depending on tooth root’s length and/or muscle insertion points • Morphology – Papule/pustule • Color – Pink (fibrotic) to yellow (purulent exudate) to red (if active inflammation) • Signs and symptoms – Painless If pain is present, then it is from infection associated with the nonvital tooth; establishment of drainage will relieve pain • Treatment – Establish drainage and eliminate the source of infection by extraction or root canal therapy on the infected, nonvital tooth Epulis fissuratum (Fig. 3.79) • Site – Vestibule adjacent to ill‐fitting denture flange • Morphology – Multiple nodules, tumor (hyperplastic tissue folds); may have secondary ulceration • Color – Pink to pink red • Signs and symptoms – Painless; composed of epithelial and fibrous hyperplasia due to reactive growth from low‐grade chronic trauma • Treatment – Remake/reline/rebase denture and surgically remove excess tissue Pyogenic granuloma (Fig. 3.80) • Site – Gingiva at interdental papilla is the most common site; any other oral mucosal site • Morphology – Papule and nodule; may be secondarily ulcerated • Color – Red • Signs and symptoms – Painless, red, firm, vascular reactive growth that easily bleeds; secondary to chronic irritant such as restoration overhang, calculus, 102 Diagnosis and Management (a) (b) (c) Figure 3.77 (a) Focal swelling of the right anterior floor of the mouth adjacent to the midline with salivary stone and acute sialadenitis (b) Patient reported a sense of floor‐of‐ mouth fullness prior to eating; biopsy yielded Wharton’s duct sialolith (c) Sialolith of Stensen’s duct near the buccal mucosal orifice Common Oral Soft Tissue Lesions 103 Figure 3.78 Nonvital right mandibular canine with associated parulis (gum boil) Figure 3.79 Ill‐fitting complete maxillary removable denture with epulis fissuratum of the vestibule foreign body material, or nonspecific traumatic event Pyogenic granuloma occurs more frequently in pregnant woman • Treatment – Complete removal and elimination of the trigger factor Peripheral ossifying fibroma (Fig. 3.81) • Site – Exclusively on attached gingiva, usually interdental papilla • Morphology – Papule and nodule;

hard palate most often when extranodal • Morphology – Nodule, tumor, and ulcer • Color – Pink or blue • Signs and symptoms – Painless usually, or painful especially if continued growth puts pressure on adjacent structures; often boggy and edematous; unilateral lesion that may cross midline, rarely arises bilaterally; becomes fixed, immovable with enlargement A rare hard palate midline, a highly destructive T‐cell type variant is known as midline lethal granuloma 106 Diagnosis and Management Figure 3.84 Reactive lymphoid aggregate (hyperplasia) of the right ventral tongue • Treatment – Typically radiation and chemotherapy; sometimes total surgical removal Complete medical workup is needed to rule out metastasis 11 Reactive lymphoid hyperplasia (Fig. 3.84) • Site – Lymph nodes or any oral site but particularly Waldeyer’s ring– soft palate complex, tonsils, floor of the mouth/ventral tongue, and oropharynx • Morphology – Papule/nodule; soft or firm • Color – Pink to yellow • Signs and symptoms – Asymptomatic, movable; nontender, but often tender to palpation when inflamed; secondary enlargement due to infection (stimulation from antigens) • Treatment – Excisional biopsy to confirm diagnosis, if necessary 12 Generalized gingival enlargement (non‐plaque‐related) (Fig. 3.85a,b) • Site – Marginal/papillary gingiva;
