Erythema Multiforme Limited to the Oral Mucosa in a Teenager on Oral Contraceptive Therapy

BackgroundErythema multiforme has been linked to numerous drugs and infectious agents. A link to oral contraceptive use has been reported in the past in the adult population but thus far has not been reported in children or adolescents.CaseWe report the case of an 18-yr-old female who developed oral erosions consistent with erythema multiforme two and a half weeks after initiating therapy with an oral contraceptive agent. A thorough examination for other inciting factors was negative, and the lesions slowly resolved over the course of 3 weeks.ConclusionsThis case illustrates that erythema multiforme should be considered in the differential diagnosis of adolescents with oral erosions who have been prescribed oral contraceptives.
