Multiple oral and skin lesions occurring after treatment with penicillin.

A case of erythema multiforme has been presented. Erythema multiforme may be a self-limiting or chronic disease, of varying severity. The disease is of significance to dental practitioners who may be called on to establish a diagnosis and provide appropriate referral or treatment, especially when lesions are limited to the mouth. The prognosis is generally good, although recurrence is common.
