Typical clinical features of leukoedema can be summarized as: • Asymptomatic and bilateral lesions • Present as semi-transparent and whitish gray macular lesion of buccal mucosa • Initial forms of leukoedema show filmy appearance of mucosa followed by grey white cast with coarse wrinkled surface Keratoses. A plaque has been described as a broad . Typical lesions are asymptomatic white plaques in which the oral mucosa appears thickened and folded, with a spongy texture (Figs 27-6 and 29-10 ). Clinical Features. - Oral white plaques characterised by increased keratinisation are called keratoses. Based on the clinical diagnosis, there were 59 cases (59%) of leukoplakia, 29 cases (29%) of lichen planus, six cases (6%) of lichenoid reaction, four cases (4%) of frictional keratosis and two cases (2%) of tobacco pouch keratosis. The clinical findings are critical in helping to distinguish between reactive keratosis and OPMD. Oral Pathology Flashcards We propose that the condition is due to a combination of intracellular edema and hyperkeratosis. Leukoedema is a benign condition that most likely represents a variation of normalmucosal appearance, although smoking may accentuate its features. White Surface Lesions | A Guide to Clinical Differential ... Leukoedema Leukoedema, in its primary form, is common enough to be considered a variation of normal, with some studies reporting a prevalence of up to 90% especially in dark-skinned patients because of the color contrast between the milky-white leukoedema on darker mucosa.

Clinical Features • found in patients with severe debilitating diseases, such as advanced diabetes, uremia, leukemia, malnutritional states, or heavy metal poisoning. Leukoedema and hereditary genodermatoses that may enter in the clinical differential diagnoses of frictional keratoses including white sponge nevus and hereditary benign intraepithelial dyskeratosis will be reviewed. [1,2] Oral mucosal changes can be subcategorized by clinical features into the subsequent major groups: normal variations and oral mucosal lesions (OML). Differential Diagnosis: White spongy Nevus Frictional Keratosis Witkop's Disease Clinical Features: Early stage: Filmy opalescence of the mucosa Later stages: Grayish-white cast with a coarsely wrinkled surface Location: Most of buccal mucosa extending onto the Lips, Seen noticeable along the occlusal line . Cause - Fordyce granules are normal sebaceous glands. [7] The incidence of OMLs is thought to extend with age, because of physiological changes within the oral cavity and also because of the sustained impact of risk habits. Almost 90% of blacks and45% of whites exhibit the filmy, opalescent quality of the buccal mucosa that characterizesleukoedema. Leukoedema lesions disappear when the mucosa is stretched, which helps to differentiate it from other white lesions in the mouth. An extremely high incidence of leukoedema of the oral mucosa was found clinically in this study of 430 patients, and the possibility that it is a variation of normal should be considered. LEUKOEDEMA; Leukoedema is a common normal variation of the oral mucosa. Leukoedema and white spongy nevus can be easily diagnosed by looking the characteristic clinical features of the two conditions.
