Geographic tongue is an inflammatory disorder characterized by asymptomatic erythematoud patched with serpiginous borders. Clinically the appearance is of multifocal, circinate, irregular patches bonded by slightly elevated, white colored keratotic bands. Several etiological factors have been proposed. The conditions may remain asymptomatic or patients may present with complains of pain and burning sensation. We report a case of geographic tongue in a 6 year old boy with review of current concept in causes and management.
