Mucosal vitiligo in angles of the mouth: clinical and fluorescence aspects.

Vitiligo is the most common depigmenting, chronic acquired disease of the skin and mucosa. However, vitiligo of an unclassified type and mucosal subtype affecting only one area of the mucosa is considered quite uncommon. The diagnosis of vitiligo, regardless of its type, is clinical. Nonetheless, a device that allows the visualization of the tissue fluorescence may be useful for confirming the diagnosis. We present the use of wide-field optical fluorescence device for complementary examination and diagnosis of unusual cases of mucosal vitiligo located only in angles of the mouth.
