Benign migratory glossitis, otherwise known as Geographic tongue, is an inflammatory condition of the tongue of unknown etiology. It is commonly referred to as Erythema migrans. The dorsum and lateral margins of the tongue are the most common sites for the lesion. This lesion is characterized by altering patterns of serpentine white lines surrounding areas of smooth, depapillated mucosa. The center of the lesion appears erythematous with white serpentine borders around it, resembling a "Map." The white border represents the regenerating filiform papillae, keratin, and neutrophils. The lesions have slightly raised, well-developed white margins that cannot be scraped off. Changes in the location and pattern of the lesion are observed every few days, giving it the name "Migratory." Histologically, the process is superficial and shows desquamation of the keratin layers of papillae along with inflammation of the corium.
