How can i tell if i have a hairy leukoplakia?

Context is important: Hairy leukoplakia appears as a white, adherent thickening, usually located on the side of the tongue, but occasionally elsewhere on the tongue, on the gums, or the lining of the cheek. Because its appearance is similar to other conditions, identification relies on the simultaneous presence of immune system depression from disease (e.g., HIV infection, leukemia), or immunosuppressive therapy.

Oral Medicine Dentis: Hairy leukoplakia is associated with advanced hiv, but is rarely seen now when patients are treated with anti-retroviral therapy. Oral candida, with white patches on the tongue and oral mucosa, as a similar appearance, but can be scraped off. Dry mouth can lead to white hairy tongue. A number of other lesions have white appearances and should be evaluated by a qualified dentist.
