Oral leukoplakia is a gray patch or plaque that develops in the oral cavity and is strongly associated with smoking. [8] Leukoplakia is a firmly attached white patch on a mucous membrane which is associated with increased risk of cancer. [4] [5] The edges of the lesion are typically abrupt and the lesion changes with time.
The most common appearance of hyperplastic candidiasis is a persistent white plaque that does not rub off. The lesion may be rough or nodular in texture. [ 10 ] Hyperplastic candidiasis is uncommon, accounting for about 5% of oral candidiasis cases, [ 8 ] and is usually chronic and found in adults.
WSN presents most commonly in the mouth, as thickened, bilateral, symmetrical white plaques with a spongy, corrugated or velvety texture. Lesions are typically present on the buccal mucosa, but may also affect the labial mucosa, alveolar ridge, floor of the mouth, ventral surface of the tongue, lip vermillion or soft palate.
Candidiasis is a fungal infection due to any species of the genus Candida (a yeast). [4] When it affects the mouth, in some countries it is commonly called thrush. [3] Signs and symptoms include white patches on the tongue or other areas of the mouth and throat. [3]
Hairy leukoplakia is a white patch on the side of the tongue with a corrugated or hairy appearance. It is caused by Epstein-Barr virus (EBV) and occurs usually in persons who are immunocompromised, especially those with human immunodeficiency virus infection/acquired immunodeficiency syndrome (HIV/AIDS).
A differential diagnosis between oral candidiasis and GT, two similar looking conditions, can be established through a careful and thorough examination. GT is a keratotic lesion which can be described as a round or irregular shaped white plaque, cannot be scraped off and is normally self-resolving. [18]
Oral candidiasis: Also known as thrush, herpetic gingivostomatitis can often be differentiated from these microorganism/bacterial causing white plaques on the palate, buccal mucosa, tongue, oropharynx etc. [16] Apthous stomatitis: They are commonly known as apthous ulcers, and are characterized by grey membranes and peripheral erythema.
Frictional keratosis: This typically presents as white plaques on the oral mucosa due to mechanical trauma. When the cause of frictional keratosis is removed the white patch may resolve. Hyperplastic reactive lesions or nodular swellings: These occur in the oral mucosa due to low grade inflammation or trauma. They develop where the mucosa is ...
