Leukoedema - Oral Mucosal Lesion
Black patients are noted to have a higher incidence of this and it may be because the whiteness of leukoedema shows up better overlying a pigmented mucosa.
Patients do not experience any symptoms with this condition.

Differential Diagnosis & Pitfalls
- Lichen planus – This may have a reticular appearance but this does not disappear when the area is stretched.
- Chronic use of astringent mouth washes can cause leukoedema initially but this may progress to actual desquamation and peeling of the mucosa.
- Chronic bite injury (cheek chewing) – This has a shaggy, irregular surface configuration and may occur in a background of leukoedema.
- Early smokeless tobacco keratosis – This may appear similar since the etiology is the same (topical injury).
- Leukoplakia – This is denser in color and texture.
- Inherited mucosal disorders such as Canon's white sponge nevus and hereditary benign intraepithelial dyskeratosis have a denser appearance and there is usually a family history of the disorder.
- Candidiasis – This is usually painful and appears as curdy papules and plaques with surrounding erythema.
