Oral syphilis—re-emergence of an old disease with oral manifestations

Abstract

Three representative cases of oral primary syphilis are presented. We wish to highlight the resurgence of this disease, which has occurred recently in the western world, particularly in Europe and the United States of America. Since the initial presentation may be oral, it is important to include syphilis in the differential diagnosis of patients presenting to oral diagnostic clinics with atypical oral ulceration. Recent developments in the serological diagnostic tests and treatment are reviewed. Early diagnosis and treatment has significant implications, not only for the patient, but also for previous and future transmission to contacts. Early syphilis is a highly infectious disease in which the lesions heal spontaneously, despite inappropriate treatment which may appear curative, and yet the patient remains infectious. It is therefore important that clinicians maintain a high clinical index of suspicion and crucial that an accurate diagnosis be made at presentation.
