Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Smoker''s melanosis is characterized by flat, irregular hyperpigmentation of the connective tissue underlying the oral mucosa resulting from tobacco smoking. Basal cells and macrophages in the underlying connective tissue contain unusual amounts of melanin, which creates the darker pigmentation. Macrophages are unable to degrade all of the melanin, a phenomenon known as melanin incontinence. A study in Sweden showed that 21.5% of smokers and 3% of nonsmokers had lesions that could be classified as smoker''s melanosis. Smoking is the cause in most cases, although similar hyperpigmentations can sometimes be seen in nonsmokers. Similar hyperpigmentations can be due to physiological pigmentation, amalgam tattoo, suntan, drug-related melasma, Addison''s Disease, or Post-inflammatory hyperpigmentation (also known as adrenal insufficiency).
