Resurgence of syphilis:a diagnosis based on unusual oral mucosa lesions

2009

Background Known as “the great imitator,” secondary syphilis may clinically manifest itself in myriad of ways, involving different organs (including the oral cavity), and mimicking, both clinically and histologically, several diseases, thereby making diagnosis a challenge for clinicians. Case report We highlight an interesting case of a 45-year-old man on whose diagnosis of secondary syphilis was based on the presence of unusual oral lesions, consisting of a well delimited, raised, nonhomogeneous, and corrugated white plaque on the right buccal mucosa which mimicked, clinically and histologically, a “leukoplakia-like” plaque and several whitish oral mucous patches localized on the lower lab…

Comparative analysis of immunohistochemistry, polymerase chain reaction and focus-floating microscopy for the detection of Treponema pallidum in muco…

Summary Background  The incidence of syphilis is increasing in many parts of the world including a re-emergence in Western Europe and North America. Depending on the disease stage, direct detection of Treponema pallidum in mucocutaneous lesions of syphilis may be difficult and histopathological findings are not always straightforward. Thus, the correct histological diagnosis may be challenging. Objectives  Comparatively to evaluate the evidence for infection with T. pallidum by immunohistochemistry (IHC), polymerase chain reaction (PCR) and focus-floating microscopy (FFM). Methods  A series of 86 paraffin-embedded skin biopsy samples from patients with primary, secondary or tertiary syphili…

Oral findings in secondary syphilis

2018

Background Syphilis is a sexually transmitted disease caused by Treponema pallidum. However, there are of hematogenic and vertical transmission. All health care professionals must be aware of the manifestations of this condition, such as oral lesions. Objectives This study to analyze and compare four clinical cases of syphilis that were diagnosed based on lesions in the oral cavity with published literature. Material and Methods Four patients with a confirmed sorologic and clinical diagnosis of syphilis were examined, confirmated from manifestation of oral lesions together with analysis of serological laboratory tests and histopathological analyses. Results Lesions were found in classic sit…

Fluorescenzserologischer Nachweis eines in Syphilitikerseren vorkommenden Antik�rpers gegen ein hitzestabiles Antigen der Reiter-Treponemen

1967

An insgesamt 88 Syphilitikerseren wurde der FTA-Test mit erhitzten Reiter-Treponemen durchgefuhrt. 71 mal reagierte die Serumverdunnung von 1∶100, in 53 Fallen eine solche von 1∶500 positiv. Von 53 Kontrollseren waren nur 2 bei der Verdunnung von 1∶100 positiv. Hieraus wird auf das Vorkommen eines hitzestabilen gemeinsamen Gruppen-Antigens in Reiter-Treponemen und T. pallidum geschlossen. Die Zugehorigkeit dieses Antigens zu den Lipopolysacchariden wird diskutiert. Menschliche Antikorper gegen dieses Antigen sind vorerst nur fluorescenzserologisch nachzuweisen.
