Benign migratory glossitis, or geographic tongue, is usually an asymptomatic inflammatory disorder of unknown etiology that affects the epithelium of the tongue. Local loss of filiform papillae leads to ulcer-like lesions that rapidly change the color and size. Histopathologic findings parallel the clinical appearance, and may have a psoriasiform pattern. The disorder is characterized by exacerbations and remissions. In most cases, patients do not require treatment other than reassurance about the benign nature of the disorder.
