Tobacco, alcohol, chronic local friction, and Candida albicans are important predisposing factors. [44]:480[29]:806, Diseases of the skin and appendages by morphology, CS1 maint: DOI inactive as of January 2021 (. The edges of the lesion are typically abrupt and the lesion changes with time. Larger white patches are more likely to undergo malignant transformation than smaller lesions. [2] Since smoking and alcohol consumption also places individuals at higher risk of tumors occurring in the respiratory tract and pharynx, "red flag" symptoms (e.g. However, the efficacy of this treatment modality cannot be assessed due to insufficient available evidence. [32] However, this definition is inconsistently applied in the medical literature, and some refer to any oral white patch as "leukoplakia". [1] Smokers are much more likely to suffer from leukoplakia than non-smokers. Along with red and bulging lesions (speckled leukoplakia or erythroplasia), which are more likely to show precancerous changes; Hairy leukoplakia. Speckled or Erythroleukoplakia 3. White gums are caused by a condition known as leukoplakia. Human papillomavirus (HPV) 16 and 18 have been correlated with head and neck cancers. [1], Candida in its pathogenic hyphal form is occasionally seen in biopsies of idiopathic leukoplakia. [6] The percentage of people affected is estimated at 1–3%. oral leukoplakia, leukoplakia of the urinary tract, including bladder leukoplakia or leukoplakia of the penis, vulvae, cervix or vagina. Speckled leukoplakia is a rare type of leukoplakia with a very high risk of premalignant growth and mortality rate. [27] Accepted definitions of leukoplakia have changed over time and are still controversial. Leukoplakia cannot be rubbed off the mucosa,[13] distinguishing it readily from white patches such as pseudomembraneous candidiasis, where a white layer can be removed to reveal an erythematous, sometimes bleeding surface underneath. The sites of a leukoplakia lesion that are preferentially biopsied are the areas that show induration (hardening) and erythroplasia (redness), and erosive or ulcerated areas. Mean age was 57 years old and soft palate was the site affected in 77% of the cases. Although this type of leukoplakia may show dysplasia, the potential for malignant transformation is unknown. [18], Oral hairy leukoplakia is a corrugated ("hairy") white lesion on the sides of the tongue caused by opportunistic infection with Epstein-Barr virus on a systemic background of immunodeficiency, almost always human immunodeficiency virus (HIV) infection. Speckled leukoplakia is a rare type of leukoplakia with a very high risk of premalignant growth and mortality rate. n. A speck or small spot, as a natural … [6] Risk factors for formation inside the mouth include smoking, chewing tobacco, excessive alcohol, and use of betel nuts. Homogenous leukoplakia Localized or extensive white patch Surface is corrugated Like a beach at ebbing tide Wrinkled pattern{cristae} Dry, cracked-mud appearance with irregular edges [22], Leukoplakia of the esophagus is rare compared to oral leukoplakia. Verrucous leukoplakias are usually heavily keratinized and are often seen in elderly people. leukoplakia), or malignancy (e.g. Older people with white patches are at higher risk. leukoplakia buccalis (leukoplakia of the buccal mucosa) or leukoplakia lingualis (leukoplakia of the lingual mucosa). the vast majority of oral leukoplakia lesions will remain benign. Nonhomogeneous leukoplakia: A predominantly white or white and red lesion that may be irregular, flat, nodular, or corrugated. The malignant potential is seemingly low, and few cases of anal carcinoma have been reported associated with anal leukoplaka.[26]. Leukoplakia could also be considered according to the affected site, e.g. Proliferative verrucous leukoplakia. [27] This hides the normal pink-red color of mucosae (the result of underlying vasculature showing through the epithelium). Epstein-Barr virus has been documented to be an agent in nasopharyngeal carcinoma and associated with oral hairy leukoplakia, lymphoproliferative disease, B-cell lymphomas, a… Define speckle. This finding is uncommon in the mouth, and carries a risk of malignant transformation. [30] Cigarette smoking may produce a diffuse leukoplakia of the buccal mucosa, lips, tongue and rarely the floor of mouth. p53) are antagonistic to oncogenesis. [6] Tissue biopsy generally shows increased keratin build up with or without abnormal cells, but is not diagnostic. Speckled Leukoplakia (redirected from Speckled Oral Leukoplakia) A white flecked or finely nodular lesion over an atrophic erythematous base that may be seen in a background of erythroplasia which is flat or depressed below the surrounding mucosa. There are many known conditions which present with a white lesion of the oral mucosa, but the majority of oral white patches have no known cause. [3], The term has been incorrectly used for white patches of any cause (rather than specifically referring to idiopathic white patches) and also to refer only to white patches which have a risk of cancerous changes. [3] Other methods involve the use of illuminescence, relying on either the property of normal autoflorescent molecules in mucosa such as collagen and keratin which is lost from areas of dysplasia or carcinoma under blue light, or by initially staining of the mucosa with toluidine blue or dilute acetic acid and examination under white light. Leukoplakia is a condition in which one or more white patches or spots (lesions) forms inside the mouth. [4][7] One specific type is common in HIV/AIDS. Mayo Clinic defines leukoplakia as a condition where thick, white spots or patches form on the gums, inner cheeks, and bottom of the mouth. [43] According to one source from 1961, leukoplakia can occur on multiple different mucous membranes of the body, including in the urinary tract, rectum, vagina, uterus, vulva, paranasal sinuses, gallbladder, esophagus, eardrums, and pharynx. It consists of fuzzy, white patches on the tongue (hence, its name) and less frequently, elsewhere in the mouth. Proliferative Verrucous Leukoplakia 19. Learn more from WebMD about how leukoplakia is treated. [8]Vitamins C and E have also been studied with regards a therapy for leukoplakia. One suggested program is every 3 months initially, and if there is no change in the lesion, then annual recall thereafter. Cancer Prev. This requires experience as it is a difficult skill to learn. Granular or Nodular Leukoplakia 2. These types of leukoplakia are often associated with mild complaints of localised pain or discomfort. Mechanical trauma, e.g. [8] Other treatments that have been studied include photodynamic therapy. The risk of malignant transformation is similar to normal mucosa. [42], The term leukoplakia was coined in 1861 by Karl Freiherr von Rokitansky, who used it to refer to white lesions of the urinary tract. White patches in your mouth are a sign of leukoplakia. Definition Leukoplakia is a clinical term, and the lesion is defined as awhite patch or plaque, firmly attached to the oral mucosa, that cannot be classified as any other disease entity. Homogenous Leukoplakia Clinical features Homogenous white patch/ plaque No red component Fine, white, grainy texture. Erythroplakia is analogous to the term leukoplakia which describes white patches. Leukoplakia, or white and gray patches inside the mouth, may be caused by irritation. A frictional keratosis will generally be adjacent to a sharp surface such as a broken tooth or rough area on a denture and will disappear when the causative factor is removed. [27] Some leukoplakias with dysplasia reduce or disappear entirely following use of antifungal medication. [1] Candida in association with leukoplakia should not be confused with white patches which are primarily caused by candida infection, such as chronic hyperplastic candidiasis ("candidal leukoplakia"). Recurrence of leukoplakia was observed in approximately 40% of patients in whom complete clinical remission occurred if topical applications were discontinued. [1], Ultraviolet radiation is believed to be a factor in the development of some leukoplakia lesions of the lower lip, usually in association with actinic cheilitis. Advanced forms may develop red patches. [1], Leukoplakia is more likely to develop in areas of epithelial atrophy. [2][8] Homogenous leukoplakia is usually slightly elevated compared to surrounding mucosa, and often has a fissured, wrinkled or corrugated surface texture,[2] with the texture generally consistent throughout the whole lesion. [2], Many different topical and systemic medications have been studied, including anti-inflammatories, antimycotics (target Candida species), carotenoids (precursors to vitamin A, e.g. [27][33], The epithelium may show hypertrophy (e.g.
