As with basal cell excision, however, depends on the size and location of the carcinoma, several fac to rs contribute to the etiology of lesion. In addition, carcinogens such as tars, oils, surgical options, such as chemotherapy and radiation ther and arsenicals; exposure to x-rays; and the presence of skin apy, are occasionally used to treat patients under special diseases that cause scarring, such as severe burns and discoid circumstances.

Focal (Frictional) Hyperkera to sis White Lesions Associated with Smokeless Tobacco Etiology and Pathogenesis Nicotine S to matitis To date, the cause of leukoedema has not been established. Hairy Leukoplakia Fac to rs such as smoking, chewing to bacco, alcohol ingestion, Hairy Tongue bacterial infection, salivary conditions, electrochemical inter Dentifrice-Associated Slough actions, and a possible association with cannabis use have Preneoplastic and Neoplastic Lesions been implicated, but none are specifcally proven causes. Actinic Cheilitis Actinic Kera to ses (Solar Kera to ses) Clinical Features Leukoedema is usually discovered as an incidental fnding. Idiopathic Leukoplakia It is asymp to matic and symmetrically distributed in the Other White Lesions buccal mucosa, and to a lesser extent over the labial mucosa. Geographic Tongue It appears as a gray-white, difuse, flmy, or milky surface Lichen Planus alteration (Figure 3-1). In exaggerated cases, a whitish cast Lupus Erythema to sus with surface textural changes, including wrinkling or cor Nonepithelial White-Yellow Lesions rugation, may be seen.

Lipoma Diferential Diagnosis White sponge nevus, hereditary benign intraepithelial dyskera to sis, the response to chronic cheek biting, and li Lesions of the oral mucosa that appear clinically white re chen planus all may show clinical similarities to leukoedema. Treatment and Prognosis White or yellow-white lesions may also be due to fbrinous Treatment is not necessary because the changes are innocu exudate covering an ulcer, submucosal deposits, surface ous and no malignant potential exists. Once tissue diagnosis is confrmed, symmetrically, and treatment is generally not required. The pre sentation intraorally is almost always bilateral and symmetric Hereditary Benign Intraepithelial Dyskera to sis and usually appears early in life, typically before puberty.

It has been proposed that abnormali at the corneal limbus, and oral white lesions. Preceding the ties in this calcium pump function interfere with cell bulbar conjunctivitis are foamy gelatinous plaques that repre growth and diferentiation of calcium-dependent processes. Oral lesions consist of soft, asymp to matic, white folds and Clinical Features plaques of spongy mucosa. Areas characteristically involved in Onset occurs between the ages of 6 and 20 years. The disease has clude the buccal and labial mucosa and the labial commissures, a predilection for the skin, with 13% of patients demonstrating as well as the foor of the mouth and lateral surfaces of the oral lesions. Skin manifestations are characterized by small, skin to ngue, gingiva, and palate. The dorsum of the to ngue is usually colored papular lesions, symmetrically distributed over the face, spared. Oral lesions are generally detected within the frst year trunk, and intertriginous areas. The papules eventually coalesce of life, with a gradual increase in extent until midadolescence. Lesions may also occur unilaterally or in a zosteriform pattern (lesions follow a derma to me). Tickening of the palms and soles (hyperkera to sis palmaris et plantaris) by excessive kera to tic tissue is not uncommon. Lesions typically appear as small, whitish papules, producing an overall cobbles to ne appearance. Features include: (1) formation of suprabasal lacunae (clefts) containing acantho lytic epithelial cells, (2) basal layer proliferation immediately be low and adjacent to the lacunae or clefts, (3) formation of verti cal clefts that show a lining of parakera to tic and dyskera to tic cells, and (4) the presence of specifc benign dyskera to tic cells, called corps ronds and grains. Corps ronds are large, keratinized squamous cells with round, uniformly basophilic nuclei and in tensely eosinophilic cy to plasm. Treatment and Prognosis The goal of treatment is to improve the appearance of the skin lesions, reduce symp to ms, and prevent or treat infective complications. Topical corticosteroids and the vitamin A analog retinoic acid have been used efectively, but long-term therapy is to lerated poorly. The disease is chronic and slowly progressive; remissions may be noted in some patients. Reactive Lesions Focal (Frictional) Hyperkera to sis Etiology Focal (frictional) hyperkera to sis is a white lesion that is related to chronic rubbing or friction against an oral mu cosal surface. Clinical Features Friction-induced hyperkera to ses occur in areas that are commonly traumatized, such as the lips, lateral margins of the to ngue, buccal mucosa along the occlusal line, and edentulous alveolar ridges (Figures 3-4 to 3-7; Box 3-2). Chronic cheek or lip chewing may result in opacifcation (keratinization) of the afected area. His to pathology As the name indicates, the primary microscopic change is hyperkera to sis (Figure 3-8). Disease Features/Action Edentulous ridges and vestibules may be affected in denture wearers. Smokeless to bacco is also used in Sweden in the form of snus, a nonfermented type of moist to bacco with lower concentrations of harmful nicotine and to bacco de rivatives versus those types of fermented smokeless to baccos traditionally used in the United States. Note that the the Indian subcontinent and Southeast Asia, use of smoke epithelial maturation pattern is otherwise normal. Patients should be advised to dis The general increase in smokeless to bacco consumption continue the causative habit, or the ofending to oth or has been related to peer pressure and increased media adver denture should be smoothed. The lesion should resolve, or tising, which often glamorizes the use of smokeless to bacco, at least should be reduced in intensity, over time, helping to or snuf dipping. Resolution of the lesion intense smokers and those who wish to avoid smoking may would allow unmasking of any underlying lesion that may gravitate to this alternative. If the clinical diagno exposure to smokeless to bacco include the development of sis is in doubt, a biopsy should be taken. Control of the habit causing the lesion Etiology should result in clinical improvement. No malignant A causal relationship has been documented between smoke potential exists. Although all forms of smokeless to bacco may cause alterations in the oral mucosa, White Lesions Associated with Smokeless snuf (particulate, fnely divided, or shredded to bacco) ap Tobacco pears to be more likely to cause oral lesions than does chew Marked geographic and gender diferences in to bacco use ing to bacco. In the United States a relatively high efects of to bacco with infammation and kera to sis. At the prevalence of smokeless to bacco users are found in the molecular level, altered cell signaling in damaged cells has southern and western states. Dysplastic changes may follow, but Rhode Island is less than 1% of the population, but in West with a low potential risk of malignant change. It has been demonstrated that leukoplakia can be Prevalence associated with regional use. The most common area of Treatment involvement is the mucobuccal fold of the mandible in the Discontinue use incisor or the molar region. The mucosa develops a granular Biopsy if ulcerated, indurated, or persistent Slight risk of malignant transformation with long-term use to wrinkled hyperkera to tic appearance. Less often, an erythro plakic or red component may be admixed with the white kera to tic component. The lesions are generally painless and asymp to matic, and their discovery is often incidental to routine oral examination. His to pathology Slight to moderate parakera to sis, often in the form of spires or chevrons, is noted over the surface of the afected mucosa (Figure 3-11). Epithelial dysplasia may occasionally develop in these lesions, espe cially among long-time users of smokeless to bacco. On oc casion, a difuse zone of basophilic stromal alteration may be seen, usually adjacent to infamed minor salivary glands. Treatment and Prognosis With discontinuation of smokeless to bacco use, some lesions may disappear after several weeks. Note incisal edge abrasion wear of transformation to verrucous or squamous cell carcinoma, and periodontal disease. Nicotine S to matitis Etiology Nicotine s to matitis is a common to bacco-related form of kera to sis. It is typically associated with pipe and cigar smok ing, with a positive correlation between intensity of smoking and severity of the condition. The importance of the direct to pical efect of smoke can be appreciated in instances in which the hard palate is covered by a removable prosthesis, resulting in sparing of the mucosa beneath the appliance and hyperkera to sis of exposed areas. Clinical Features His to pathology The palatal mucosa initially responds with an erythema to us Nicotine s to matitis is characterized by epithelial hyperplasia change followed by keratinization (Box 3-4). The minor salivary glands opacifcation or keratinization of the palate, red dots sur in the area show infamma to ry change, and excre to ry ducts rounded by white kera to tic rings appear (Figures 3-12 and may show squamous metaplasia. The dots represent infammation surrounding the minor salivary gland excre to ry ducts. Treatment and Prognosis this condition rarely evolves in to malignancy, except in indi viduals who reverse smoke. Terefore, nicotine s to matitis should be viewed as an Bacterial: tuberculosis, bacillary angioma to sis indica to r of potential signifcant epithelial change at sites Fungal: candidiasis, his to plasmosis other than the hard palate. In a small percentage of cases, hairy leukoplakia may be seen in patients with other forms of immunosuppression, particu larly those associated with organ transplantation (medical induced immunosuppression), hema to logic malignancy, Clinical Features and long-term use of systemic or to pical corticosteroids.

Clinical response is the criterion that must be applied for each patient; titration to clinical efficacy is necessary. Because there is not complete cross- to lerance among these drugs, it is usually necessary to use a lower than equianalgesic dose initially when changing drugs and to retitrate to response. Patients may require breakthrough doses of short-acting opioids during conversion to transdermal fentanyl. Available dosingformulationsofthese combination medications are being adjusted to reflect increased caution about acetaminophen to xicity. Acetaminophen doses in a single combination tablet or capsule will be limited to no more than 325 mg. Distribution ofopioid agonist-antagonists, such with severe pain because the dose of opioid is not limited as buprenorphine, for opioid use disorder is restricted in by the to xicities of the acetaminophen, aspirin, or the United States, and management issues are complex. For severe unrelieved pain, a dose increase of acting opioid required over the preceding days. The frequency of dosing ple, 24-hour opioid requirements established using should be adjusted so that pain control is continuous.
