The wandering rash of the tongue or also called erythema migrans (Lingua geographica) is a benign, inflammatory change of the surface of the tongue. It manifests itself in red spots on the surface of the tongue, which are generally surrounded by a white border that is changing continually. Typical symptoms are a burning sensation on the tongue and sensitivity especially for spicy or hot food. The symptoms can be avoided through absence of said food or through moderate consumption. Medications are normally not necessary. Therapeutic options are possible, for example with tannins or antihistamines. Although the efficiency and general effects of the aforementioned therapeutic options are not adequately documented, they have the distinct potential to alleviate the symptoms.
