Multiple, annular, erythematous lesions of the oral mucosa.

Benign migratory stomatitis is a relatively rare entity, but because of its benign nature and clinical characteristics, it should be easily recognized by the general practitioner. Biopsy is usually not indicated and treatment consists of reassuring the patient that the lesions are benign even though they may disappear, reappear, and change location; the patient should report back for periodic follow-up.
