Nicotine stomatitis is a common form of keratosis of the hard palate seen in long-term smokers.
In 1941, Thoma named the lesion stomatitis nicotine because it is almost exclusively observed in individuals who smoke tobacco.
It is commonly associated with pipe smokers, although it is seen in cigar and cigarette smoking as well. Generally, it is asymptomatic or mildly irritating.
The lesion develops due to the heat generated from the tobacco product which as result induces a reactive process causing inflammation, hyperplasia and keratinization of the palatal mucosal epithelium.
