What Is The Diagnosis?


Geographic tongue is a recurrent, benign, usually asymptomatic, inflammatory disorder of the mucosa of the dorsum and lateral borders of the tongue. Geographic tongue is characterized by circinate, irregularly shaped erythematous patches bordered by a white keratotic band (Top Image). The central erythematous patch represents loss of filiform papillae of tongue epithelium. Geographic tongue can, although rarely, present as symptomatic.
