Picture of Geographic Tongue
Geographic tongue. There is a peculiar condition of the tongue that takes the form of denudations of the lingual surface in patches of redness that shift in position from time to time over hours and days. The cause of the condition is not known; there may be some relationship to psoriasis. No treatment is effective. The condition is largely asymptomatic except for slight tingling when sharp food is taken.
