Recurrent oral erythema multiforme is a distinct, but less-well-recognized variant of the erythema multiforme group of diseases. It is characterized by recurrent blistering of the mouth, periodic recurrences, prolonged duration, and considerable morbidity. The cause is unknown; however, a number of precipitating factors have been suggested. Patients with severe involvement usually require orally administered corticosteroids for adequate control.
