Another very common cause of white patches in the mouth is frictional or irritational trauma leading to keratosis. Examples include nicotine stomatitis, which is keratosis in response to heat from tobacco smoking (rather than a response to the carcinogens in tobacco smoke). The risk of malignant transformation is similar to normal mucosa.
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 ...
White sponge nevus (WSN) is an extremely rare autosomal dominant [4] condition of the oral mucosa (the mucous membrane lining of the mouth). It is caused by one or more mutations in genes coding for keratin , which causes a defect in the normal process of keratinization of the mucosa.
Smokeless tobacco keratosis (STK) [4] is a condition which develops on the oral mucosa (the lining of the mouth) in response to smokeless tobacco use. Generally it appears as a white patch, located at the point where the tobacco is held in the mouth. The condition usually disappears once the tobacco habit is stopped.
