Medical term:
leukoplakia
leukoplakia
[loo″ko-pla´ke-ah]a disease marked by the development of white thickened patches on the mucous membranes of the cheeks (leukoplakia buccalis), gums, or tongue (leukoplakia lingualis); the patches sometimes form fissures and often become malignant. They may grow into larger patches or form ulcers. Those in the mouth may in time cause pain during swallowing of food or speaking. Leukoplakia affects mostly middle-aged to elderly men, often after prolonged irritation of the mouth from such varying factors as badly fitting dentures or immoderate use of tobacco.
Treatment is aimed at removing any possible cause of physical or chemical irritation; the patient should give up tobacco and possibly also alcohol and extremely hot food. Dental attention may be necessary if teeth are uneven or dentures do not fit properly. Surgical removal of the affected area is relatively simple and may be the best means of preventing further development of the condition.

leukoplakia (vulvar)
Chronic vulvar dystrophy, see there.The term leukoplakia continues to be widely used (incorrectly) in the working gynaecological parlance; the error lies in that the term leukoplakia merely refers to the macroscopic appearance of white patches in the postmenopausal vulva, which most commonly correspond to hyper- or parakeratosis and far less commonly to carcinoma in situ or Paget's disease. The portent of vulvar leukoplakia is thus in sharp contrast to oral leukoplakia, which is generally regarded as a pre-malignant lesion.
