Recurrent erythema multiforme in a child.

A 6-year-old boy presented in September 1999 with a 2-day history of vesicular lesions on his oral mucosa and lips (Fig 1a), palms, and soles. Physical examination of the patient revealed a target lesion on the right wrist (Fig 1b). These features were compatible with erythema multiforme (EM) secondary to herpes labialis. The lesions resolved after the administration of oral acyclovir. The lesions, however, relapsed 10 weeks later.
