Tobacco is the greatest single cause of oral and pharyngeal cancer. Using tobacco increases the risk of oral cancer by 3 to 6 times [20] [9] and is responsible for around 40% of all oral cancers. [21] Smokeless tobacco (including chewing tobacco, snuff, snus) also causes oral cancer. [22] [23] [24] Cigar and pipe smoking are also important risk ...
Microscopic examination of keratinocytes scraped from the buccal mucosa. Tissue biopsy is usually indicated [5] to rule out other causes of white patches and also to enable a detailed histologic examination to grade the presence of any epithelial dysplasia. This is an indicator of malignant potential and usually determines the management and ...
a. Early lesions, blanching of the oral mucosa; b. Older lesions, vertical and circular palpable fibrous bands in and around the mouth or lips, resulting in a mottled, marble-like appearance of the buccal mucosa; Stage 3: Sequelae of oral submucous fibrosis a. Leukoplakia; b. Speech and hearing deficits
Site – gingiva, buccal mucosa, alveolar mucosa, hard palate, floor of the mouth, larynx, oesophagus, penis, vagina, scrotum. Clinical presentation: It is a slow growing, diffuse, exophytic lesion usually covered by leukoplakic patches. Invasive lesions quickly invade bones.
Mucositis is the painful inflammation and ulceration of the mucous membranes lining the digestive tract, usually as an adverse effect of chemotherapy and radiotherapy treatment for cancer. [1] Mucositis can occur anywhere along the gastrointestinal (GI) tract, but oral mucositis refers to the particular inflammation and ulceration that occurs ...
Leukoedema lesions disappear when the mucosa is stretched, which helps to differentiate it from other white lesions in the mouth. [2] The differential diagnosis is with leukoplakia , oral candidiasis , oral lichen planus , white sponge nevus , morsicatio buccarum , [ 3 ] hereditary benign intraepithelial dyskeratosis and dyskeratosis congenita.
Giant-cell fibromas are commonly located on the gingiva.The tongue is the second most common location, followed by the palate or buccal mucosa.Giant-cell fibromas are usually asymptomatic and appear as 0.5-1cm pedunculated or sessile lesions with a pebbly or bosselated surface.
Early lesions may appear as thin, translucent and granular or wrinkled mucosa. [2] [6] The later lesion may appear thicker, more opaquely white and hyperkeratotic with fissures and folds. [6] [2] Oral snuff causes more pronounced changes in the oral mucosa than tobacco chewing. [1] Snuff dipping is associated more with verrucous keratosis. [1]
