Geographic tongue has multiple irregularly shaped red flat and smooth patches on the top of the tongue. They have sharp distinct grey-white boarders. The patches move around and sometimes totally disappear for periods of time. It is also called benign migratory glossitis. Benign because it's harmless, migratory because it moves around the tongue and glossitis because the tongue is inflamed. If the patches appear on the tissues surrounding the tongue, the condition is erythema migrans.

          Geographic tongue is harmless, runs in families and is not contagious. Food allergies are probably the cause. A food diary tracking outbreaks may help. Triggers may be irritation from hot or spicy foods, alcohol, or tobacco. It's more common in people who are sensitive to the environment with allergies, eczema or asthma. Diabetics have a higher incidence. Patients with active lesions are sometimes susceptible to bacterial and fungal infections. Fortunately, it's benign and has little to no malignant potential.

          Geographic tongue goes away by itself so treatment is optional. Many patients have zinc deficiencies so zinc supplements may help. It's usually painless, however, some patients experience a burning tongue or irritating sensation. Occassionally, a patient reports a sore tongue. In these cases, it often responds to topical steroids. Topical Lidex gel applied 4 times daily, just after meals and at bedtime. Also, an equal mixture of diphenhydramine syrup or elixir, 12.5 mg per 5 mL, in combination with Kaopectate or unflavored Maalox helps. No method of treatment is succesful in curing this condition, however, most cases disappear by themselves within a short time.
