Encyclopedia Article for leukoplakia

precancerous tumour of the mucous membranes, most common in older men and usually seen on the lips or tongue, but also known to occur in women on the vagina or vulva. Leukoplakia first appears as a small, smooth, white spot but develops into a larger area of thickening with a rough texture and colour varying from white to gray; red areas within the leukoplakia pose a particularly high risk of becoming malignant. Older lesions may have numerous fissures and sores and tend to bleed after slight injury
