title: Erythema multiforme caused by Treponema pallidum in a young patient with human immunodeficiency virus infection.
abstract: Erythema multiforme (EM) is usually caused by drug reactions or virus infection. We report a case of secondary syphilis presenting as EM in an HIV-infected patient, proved by immunohistochemical staining, which is rare in the literature. It is valuable to determine the etiology of EM to optimize treatment.
