ERYTHEMA MIGRANS (Geographic Tongue)
Erythema migrans is a common benign condition that primarily affects the tongue. The characteristic lesions of erythema migrans are seen onthe anterior two-thirds of the dorsal tongue mucosa. They appear as multiple, well-demarcated zones of erythema concentrated at the tip and lateral borders of the tongue. This erythema is due to atrophy of the filiform papillae, and these atrophic areas are typically surrounded at least partially by a slightly elevated, yellow white, serpentine or scalloped border. Infrequently, patients complain of tenderness or a burning sensation but generally no treatment is indicated for patients with erythema migrans.

Geographic tongue tends to come and go it usually heals without treatment, but will recur again usually affecting a different area of the tongue. Most cases are not associated with any symptoms (asymptomatic) and the condition usually goes away without treatment. But to manage discomfort or sensitivity, the doctor may recommend medications such as: Over-the-counter pain relievers. Mouth rinses with an anesthetic. Antihistamine mouth rinses. Corticosteroid ointments or rinses. Vitamin B supplementation, in some cases.
