[Benign migratory glossitis: an enigmatic lesion].

Abstract

Although benign migratory glossitis, commonly called "geographic tongue," is frequently observed, we still have not been able to determine its etiology. While the condition is usually asymptomatic, the spectacular appearance of the lesion frequently causes the patient considerable worry. Based on a review of the literature, different theories on the lesion's etiology as well as therapeutic modalities will be discussed.
