Oral Leukoplakia and Risk of Progression to Oral - PubMe

  1. Background: The optimal clinical management of oral precancer remains uncertain. We investigated the natural history of oral leukoplakia, the most common oral precancerous lesion, to estimate the relative and absolute risks of progression to cancer, the predictive accuracy of a clinician's decision to biopsy a leukoplakia vis-à-vis progression, and histopathologic predictors of progression

Leukoplakia treatment is most successful when a lesion is found and treated early, when it's small. Regular checkups are important, as is routinely inspecting your mouth for areas that don't look normal. For most people, removing the source of irritation ― such as stopping tobacco or alcohol ― clears the condition Leukoplakia is a premalignant lesion of the oral mucosa that presents as a white lesion or patch that cannot be characterized clinically or histopathologically as any other entity. Proliferative verrucous leukoplakia is a malignant form of leukoplakia of unknown etiology and is thought to be associated with human papilloma virus (HPV). It starts as a slow-growing, persistent, multifocal lesion.

Epidermal metaplasia is a histological correlate to a white patch on the surface of a mucous membrane that cannot be rubbed off, known as leukoplakia. 1 It is a common finding in oral mucosa, but rare in esophageal mucosa. 1,2 The etiology of this condition in the esophagus is unclear and thought to be associated with esophageal tobacco and. Proliferative verrucous leukoplakia (PVL) is a rare type of oral leukoplakia, where white patches that have a high risk of becoming cancerous develop inside the mouth. It mainly involves the lining inside of the cheeks (buccal mucosa) and tongue Oral leukoplakia is the most common and well-defined potentially malignant lesion (1, 2) of the oral cavity. The reported annual malignant transformation rate is 1% with a total lifetime risk of 42% (2-4)

What is Leukoplakia? Leukoplakia is a precancerous condition of the mouth, i.e., the stage before development of cancer. It leads to thick white patches on the gums, inner cheeks, tongue, lower lip.. Oral leukoplakia, as traditionally defined by the World Health Organization (WHO), is a predominantly white lesion of the oral mucosa that cannot be characterized as any other definable lesion. Kramer IR, Lucas RB, Pindborg JJ, et al. Definition of leukoplakia and related lesions: an aid to studies on oral precancer

Oral precancerous lesions are defined as a morphologically altered tissue in which cancer is more likely to occur than in its apparently normal counterpart [1-4].Under this definition, leukoplakia, erythroplakia, and palatal keratosis associated with reverse smoking are categorized as precancerous lesions [3, 4].Oral leukoplakia is the most common disease among precancerous lesions.

The majority of leukoplakias, however, do not show evidence of ED and yet MT of these lesions is well-recognized Oral leukoplakia is defined as a predominantly white lesion of the oral mucosa that cannot be characterized as any other definable lesion. It is the most common potentially malignant disorder. A risk factor for malignant transformation of OL is Candida invasion. [PubMed: 7529754]. 2. Ribeiro AS, Salles PR, da Silva TA, Mesquita RA. A. Oral hairy leukoplakia (OHL) is an Epstein-Barr virus (EBV) related lesion seen in severely immunocompromised patients especially, those with concomitant human immunodeficiency virus (HIV) infection. It has been rarely reported in immunocompetent patients. OHL most often presents on the lateral border of the tongue as an asymptomatic, white, and corrugated plaque that does not rub off. With.

As mentioned above, most PVL cases processed to malignancy over many years, sometimes 20 years. However, this report described a case of rapid progress, which had malignant.

Leukoplakia affects the mucous membranes of the mouth. The exact cause is not known. It may be due to irritation such as: Rough teeth. Rough places on dentures, fillings, and crowns. Smoking or other tobacco use (smoker's keratosis), especially pipes. Holding chewing tobacco or snuff in the mouth for a long period of time An abnormal patch of white tissue that forms on mucous membranes in the mouth and other areas of the body. It may become cancer. Tobacco (smoking and chewing) and alcohol may increase the risk of leukoplakia in the mouth.

  1. Oral leukoplakia (OL) is the most potentially malignant lesion of the oral cavity. 1, 2 The World Health Organization defines leukoplakia as A white plaque of questionable risk having excluded (other) known diseases or disorders that carry no increased risk for cancer. 3, 4 Estimates of the global prevalence of OL range from 0.5% to 3.46%.
  2. Vocal cord leukoplakia is a clinical diagnosis describing a whitish patch or a plaque on the glottis. It does not imply the histopathological figures and prognosis [1, 2].While the term leukoplakia was first used by Schwimmer in 1877 to describe a whitish lesion of the tongue [], laryngeal leukoplakia was first described in a patient by Durant in 1880

Oral hairy leukoplakia (OHL) is an oral mucosal lesion that is associated with Epstein-Barr virus infection. It commonly presents as an asymptomatic, non-removable white patch on the lateral borders of the tongue in individuals who are immunocompromised. Historically, OHL was thought to be pathognomonic of HIV infection; however, it is now an established phenomenon in a range of conditions. Oral leukoplakia is a focal white plaque varying in size and shape without any specific clinical or histological characteristic. Hence the diagnosis of leukoplakia is established by a process of exclusion, ruling out all other causes of white lesions such as candidiasis, white sponge nevus, leukoedema, frictional keratosis, etc. Shiu MN, Chen THH, Chang SH, Hahn LJ.

Causes of Leukoplakia Leukoplakia is caused by tobacco use, and this includes both chewing and smoking. Although its not a proven cause, long term alcohol use and other chronic irritants can contribute to Leukoplakia. 8. Sources -Dugdale, D. C., Schwartz, S., & Zieve, D. (2011, July 20). Leukoplakia.

An association with human papillomavirus (HPV) infection, particularly strains 16 and 18, has been implicated in some cases. [] Furthermore, because multiple cancers occur in proliferative verrucous leukoplakia-afflicted patients (ie, field-cancerization phenomenon), this suggests an infectious agent is responsible for the.

Leukoplakia is usually harmless. Patches in the mouth often clear up in a few weeks or months after the source of irritation is removed. In some cases, the patches may be an early sign of cancer.

Oral leukoplakia (OL) is the best-known potentially malignant. Although the principle of systemic treatment to prevent the progression of oral premalignant lesions (OPL) has been demonstrated, there remains a lack of consensus about an optimal approach that balances clinical efficacy with toxicity concerns. Recent advances in cancer therapy using approaches targeting the tumor immune microenvironment (TIME) including immune-checkpoint inhibitors indicate. There are over 64,000 citations in Pubmed dating back as far as 1887. Much has been learned over the past 129 years with a recent burst in therapeutic options (mostly anti-inflammatory) with newer medications in development that are neuroprotective and/or neuroreparative. However, with all these advancements the cause of MS remains elusive

The objective of this study was to investigate the biological role of transglutaminase 3 (TGM3) in malignant transformation of OL and its clinical value for predicting oral squamous cell carcinoma (OSCC) risk in patients with OL.
