Leukoedema
Leukoedema (also spelled leucoedema) is a blue, grey or white appearance of mucosae, particularly the buccal mucosa (the inside of the cheeks); it may also occur on the mucosa of the larynx or vagina. It is a harmless and very common condition. Because it is so common, it has been argued that it may in fact represent a variation of the normal appearance rather than a disease,〔 but empirical evidence suggests that leukoedema is an acquired condition caused by local irritation.〔 It is found more commonly in black skinned people and tobacco users. The term is derived from the Greek words leuko-, "white" and οἴδημα—oídēma, "swelling". ==Signs and symptoms== There is a diffuse, gray-white, milky opalescent appearance of the mucosa which usually occurs bilaterally on the buccal mucosa. Less often, the labial mucosa, the palate or the floor of mouth may be affected. The surface of the area is folded, creating a wrinkled, white streaked lesion.〔 Apart from the appearance, the lesion is entirely asymptomatic.〔
