Geographic Tongue

Geographic tongue (benign migratory glossitis) is a benign inflammatory condition that affects approximately 2% of the world’s population. The classic manifestation is a maplike distribution of erythema caused by atrophy of the filiform papillae of the tongue, surrounded by a white hyperkeratotic rim. The lesions typically resolve spontaneously without sequelae but can develop quickly in other areas of the tongue.
