Annular Syphilid Mimicking Tinea Corporis / 대한피부과학회지

ABSTRACT

Syphilid has been called the "great imitator" of skin disease, and it can have protean clinical manifestations and it may present with unusual lesions. Annular syphilid, which can mimic sarcoid, granuloma annulare, Sweet syndrome or tinea corporis, is a rare variant of syphilid. We report here on a case of annular syphilid that mimicked tinea corporis in a 29-year-old female who showed a three month history of multiple, pruritic, well-demarcated annular scaly erythematous patches with central clearing and an elevated border on the trunk and both upper extremities. Direct mycological examination and culture did not result in finding any fungal elements, and annular syphilid was confirmed according to the histopathologic and serologic findings. She and her boyfriend were treated with benzathine penicillin G, and the skin lesions disappeared completely.
