Analysis of Treponema pallidum Strains From China Using Improved Methods for Whole-Genome Sequencing From Primary Syphilis Chancres.

BACKGROUND: Whole-genome sequencing (WGS) of Treponema pallidum subspecies pallidum (TPA) has been constrained by the lack of in vitro cultivation methods for isolating spirochetes from patient samples. METHODS: We built upon recently developed enrichment methods to sequence TPA directly from primary syphilis chancre swabs collected in Guangzhou, China. RESULTS: By combining parallel, pooled whole-genome amplification with hybrid selection, we generated high-quality genomes from 4 of 8 chancre-swab samples and 2 of 2 rabbit-passaged isolates, all subjected to challenging storage conditions. CONCLUSIONS: This approach enabled the first WGS of Chinese samples without rabbit passage and provided insights into TPA genetic diversity in China.

The Great Imitator: Atypical Cutaneous Manifestations of Primary Syphilitic Chancre.

Objective To analyze the reasons of misdiagnosis of primary syphilitic chancre and strengthen the understanding of atypical features of this disease. Methods A case series of twenty-seven challenging primary syphilis patients who were not immediately recognized as chancre was included in our study. The clinical data including the patients' age, sex, skin lesions, HIV status, syphilis serologic test results, treatment, and follow-up results were collected. Hematoxylin-eosin and immunohistochemistry staining of skin biopsy sections were reviewed. Results Four female cases with extragenital chancres presenting as erythema or erosive skin lesions on the nipple were misdiagnosed as Paget's disease or eczema. The disorder of missed or misdiagnosed male cases manifested as syphilitic balanitis or multiple chancres on the penis root and adjacent pubis rather than coronal sulcus or frenum. Patients with nonreactive nontreponemal tests at initial presentation were also easily missed or misdiagnosed. Conclusion Primary syphilis presenting as multiple lesions rather than a single chancre, at atypical locations, or with a nonreactive nontreponemal test result, tends to be missed or misdiagnosed.

A nonspecific ulcer on upper lip presented as the first and sole sign of syphilis.

Syphilis, a sexually transmitted disease, can be categorized as acquired syphilis and congenital syphilis, manifesting diverse lesions involving multiple sites. Oral manifestations at the primary stage of acquired syphilis are usually characterized by its short period and non-specific varied presentations. And oral ulcers as initial and the only presentation of syphilis oral lesions are infrequent and occur in less than 2% of patients. Because of its transient nature and variable manifestations which could mimic other oral ulcerative lesions, oral syphilis presenting as sole ulceration at early stage can be easily neglected and rather difficult to diagnose. Herein, we report a 35-year-old female patient manifested a sole atypical ulceration on her upper lip for approximately 1 month. We highlighted the importance of early and accurate diagnosis, focused on the characteristics of oral chancre, and gave an insight to the differential diagnoses, which would be enlightening and useful in clinical practice.

Classical syphilitic lesions from the museum.

Syphilis is an increasingly diagnosed venereal disease which has four distinctive stages that may last over decades if appropriate treatment is not given. Review of the files of the Pathology Museum in the Faculty of Medicine at The University of Adelaide revealed three cases with classical cardiovascular and neurological findings. Case 1: An 80-year-old man with a large syphilitic aneurysm of the ascending aorta with a smaller aneurysm of the proximal descending aorta. Case 2: A 56-year-old man with chronic syphilitic meningoencephalitis with cerebral atrophy. Case 3: A 77-year-old man with tabes dorsalis. Given the increase in cases coming to medical attention in recent years due to high-risk sexual activity, migration, travel and reduced access to medical treatment, an awareness of the classical features of syphilis is appropriate as some cases will undoubtedly require medicolegal evaluation.

[Syphilis in surgery-Safe diagnosis and correct treatment]. / Syphilis in der Chirurgie ­ sicher erkennen, richtig behandeln.

BACKGROUND: The incidence of syphilis has clearly increased in Germany in recent years. This infectious disease has many forms of manifestation and can imitate surgical diseases. MATERIAL AND METHODS: Comprehensive footage of experiences in a proctological center demonstrates these manifestations and explains the correct management. RESULTS: The likelihood of confusion of syphilis with anal fissures, anogenital warts, proctitis and rectal cancer is high. CONCLUSION: Surgeons can encounter syphilis, the "chameleon of medicine" and must know the differential diagnoses.

Atypical Manifestations of Syphilis: A 10-Year Retrospective Study.

Background: The incidence of syphilis has increased in high-income countries in the past few decades, especially among men who have sex with men. In the present study, we aimed to analyze the correlations between atypical syphilis manifestations and the demographic, clinical, and laboratory features of patients and to review unusual presentations of syphilis reported in the literature. Methods: We conducted a retrospective analysis of 307 patients with syphilis diagnosed between 1 January 2013 and 31 October 2023 at the sexually transmitted infection (STI) centers of the University of Genoa and University of Foggia with both typical and atypical manifestations of disease. Results: In our series, atypical manifestations were detected in 25.8% of the patients, especially in the secondary stage of the disease. Lesions with annular morphology and lesions presenting as itchy erythematous scaly plaques with a psoriasiform appearance were the most common atypical presentations of secondary syphilis. A statistical analysis revealed that homosexual orientation, syphilis reinfection, and venereal disease research laboratory (VDRL) titers > 1:32 were correlated with atypical manifestations. Conclusions: Our study demonstrates that the spectrum of syphilis manifestations, in all the stages of the disease, is wide; atypical manifestations often pose diagnostic challenges, may delay the provision of appropriate treatment, and facilitate the spread of the infection.

Acute-Onset Lower Extremity Weakness and Urinary Retention in a Chronically Immunosuppressed Patient: Diagnosis and Management of Herpes Simplex Virus Type 2 Myelitis.

A 34-year-old immunosuppressed male presented with worsening bilateral lower extremity weakness and urinary retention accompanied by a painless clean-based chancre on his glans penis. Physical examination revealed symmetrically diminished lower extremity weakness most pronounced with hip flexion and knee extension and absent Achilles reflexes. Full MRI spine without contrast was noncontributory. Lumbar puncture showed elevated protein and total nucleated cells with lymphocytic predominance. Both CSF and serum polymerase chain reaction were positive for herpes simplex virus type 2. He received IV methylprednisolone and acyclovir and underwent four months of physical therapy with complete resolution of his neurologic deficits.

A Case of Secondary Syphilis with the Extragenital Chancre of the Lips and Tongue.

A 18-year-old male presented with ulcers of lips and tongue and erythema of trunk of more than a month duration. Laboratory examinations for syphilis showed that TRUST (+) 1:32, TPPA (+), and HIV antibodies were negative. Combined with his case history and signs, he was diagnosed with secondary syphilis with chancre of lips and tongue and was cured by injecting benzathine penicillin 2.4 million U into gluteal muscles on both sides once a week for three times. After a month, the erythema and chancre disappeared. Three months later, the TRUST test was positive, the titer was 1:8, and the TPPA was positive.

Bilateral chancre of the tongue: An unusual presentation of primary syphilis.

Syphilis is a sexually transmitted infectious disease caused by the spirochete bacterium Treponema pallidum. A characteristic lesion of primary syphilis is chancre. It can develop over genital or extra genital sites, depending on the site of contact with the infectious agent. Cases of oral syphilis have been on the rise in the previous two decades, probably because of the involvement of the oral cavity in sexual practices. We here report an unusual case of primary syphilis who presented with a painless indurated oral ulcer over the lateral borders of the tongue.

[Solitary ulcer of unknown etiology on the glans penis]. / Solitäres Ulkus unklarer Ätiologie an der Glans penis.

Ulcerations of the prepuce or foreskin of the penis are rare in the day-to-day life of a urologist. The most common differential diagnosis is invasive penile cancer, which is why other diagnoses are often overshadowed. We report a case of a syphilitic lesion which was initially misdiagnosed as penile cancer. Considering the rising incidence of syphilis worldwide, syphilis should be considered as a possible cause of any solitary penile ulcer.

Monkeypox presenting as a chancre-like rash: A case report.

BACKGROUND: Since May 2022, outbreaks of monkeypox have occurred in many countries around the world, and several cases have been reported in China. CASE SUMMARY: A 38-year-old man presented with a small, painless, shallow ulcer on the coronary groove for 8 d. One day after the rash appeared, the patient developed inguinal lymphadenopathy with fever. The patient had a history of male-male sexual activity and denied a recent history of travel abroad. Monkeypox virus was detected by quantitative polymerase chain reaction from the rash site and throat swab. Based on the epidemiological history, clinical manifestations and nucleic acid test results, the patient was diagnosed with monkeypox. CONCLUSION: Monkeypox is an emerging infectious disease in China. Monkeypox presenting as a chancre-like rash is easily misdiagnosed. Diagnosis can be made based on exposure history, clinical manifestations and nucleic acid test results.

[Tropical sexually transmitted infections Summary of the SFMTSI Scientific Day of November 9, 2023]. / Infections sexuellement transmissibles tropicales Synthèse de la Journée scientifique de la SFMTSI du 9 novembre 2023.

Sexually transmitted infections (STIs) deserve more attention today than ever in the tropics. Indeed, the emergence of monkeypox in 2022 in Western countries reminds the risk of exporting STIs from the tropics as it was already known for decades with the worldwide spread of HIV/AIDS infection from tropical Africa. Some hazards are already well identified. According to WHO 2023 report STIs are increasing in the world. Antibiotic resistance is increasing for Neisseria gonorrhoeae, and already well established for Mycoplasma genitalium, whereas Treponema pallidum has become resistant to macrolides within the last twenty years. Some neglected tropical diseases (Zika, Ebola, monkeypox) can also be sexually transmitted, sometimes months after cure (Ebola). In this setting, the use of PrEP in migrants, and in Africa, is worth to be discussed beyond traditional circles.

[Syphilitic chancre in the mouth: an unusual location. Case report]. / Chancro sifilítico en la boca: localización poco frecuente. Reporte de un caso.

Background: Syphilis is an infectious disease caused by the spirochete Treponema pallidum, transmitted mainly by direct contact with the lesion. Primary syphilis usually presents with a chancre at the site of infection, which is highly contagious and resolves without treatment. The aim of this article is to illustrate an unusual location of a syphilitic chancre, in order to consider this diagnosis within the approach to patients with oral ulcers. Clinical case: a 30-year-old man who presented a dermatosis located in the left labial commissure, characterized by a painless ulcer of 1 cm in diameter of 20 days of evolution. The patient has a history of HIV/AIDS. A punch biopsy of the dermatosis was performed, with a histopathological report compatible with syphilitic chancre and a negative VDRL result. He was treated with penicillin G benzathine showing improvement. Conclusions: Primary syphilis is characterized by the development of the syphilitic chancre, which is the first manifestation of syphilis in up to 60% of cases. Extragenital presentation is rare, with only 12-14% of all cases, and of these between 40-70% occur in the mouth, being the lips the most frequent location. Oral manifestations can represent a diagnostic challenge due to its wide spectrum of clinical presentations.

Introducción: la sífilis es una enfermedad infecciosa causada por la espiroqueta Treponema pallidum, transmitida principalmente por contacto directo con la lesión. La sífilis primaria generalmente se presenta con un chancro en el sitio de la infección, el cual es altamente contagioso y se resuelve sin tratamiento. El objetivo de este trabajo es ilustrar una localización poco común de un chancro sifilítico, ya que conocer la existencia de presentaciones poco frecuentes permitirá favorecer su sospecha al abordar las causas de úlceras orales. Caso o casos clínicos: hombre de 30 años de edad, el cual presenta una dermatosis localizada en la comisura labial izquierda, caracterizada por una úlcera no dolorosa de 1 cm de diámetro de 20 días de evolución. El paciente tiene antecedente de VIH/SIDA. Se realizó biopsia en sacabocados de la dermatosis, siendo el informe histopatológico compatible con chancro sifilítico y resultado de VDRL negativo. Fue tratado con penicilina G benzatínica, con lo que presentó mejoría. Conclusiones: la sífilis primaria se caracteriza por la aparición del chancro sifilítico, el cual es la primera manifestación de la sífilis hasta en el 60% de los casos. La presentación extragenital es rara, con solo un 12-14% de todos los casos y, de estos, entre un 40-70 % se presentan en la boca, siendo los labios la localización más frecuente. Las manifestaciones orales pueden representar un desafío diagnóstico debido a su amplio espectro de presentaciones clínicas.

Primary syphilis of the finger: report of four cases.

Although primary syphilis generally involves the genitalia, literature reports that 12% of chancres are extragenital, with the anus and oral cavity as the most frequent locations. We present hereby a case series of four chancres of the finger observed at the sexually transmitted infection centre of Milan between 2010 and 2021.

Primary syphilis without chancre - A case report of rare syphilitic balanitis of Follmann.

Introduction: Syphilitic balanitis of Follmann (SBF) is a rare condition of primary syphilis which is characterized by any kind of balanitis with or without chancre on the penis combined with the presence of swollen inguinal lymph nodes confirmed by the finding of Treponema pallidum in the lesions or by the positive serological syphilitic testing. Timely identification of the SBF is very important in properly treating the disease stopping the spread of syphilis. Case presentation: A 42year-old heterosexual male patient came to our clinic and complained of a painless, hard erythema nodule with a whitish scale in his coronal sulcus of the penis for about a week. The dermatologic examination revealed an infiltrative, hard erythematous lesion surrounding the coronal sulcus of the patient's penis, with mild erosion and a small amount of exudation. There was a whitish pseudomembrane-like covering on the surface of the erythematous lesion in the coronal sulcus, which is mimicked as candidal balanitis. The result of the fungus microscopic examination was negative, while the laboratory findings showed positive results in serologic syphilitic testing. The patient was diagnosed with primary syphilis and intramuscularly treated with a dose of benzylpenicillin of 2.4 million units. The patient's skin lesions disappeared completely 60 days after penicillin treatment. Conclusion: To our knowledge, this is the first SBF case reported in China. Syphilitic balanitis of Follmann may have variable clinical appearances. We emphasize that when balanitis with risky sexual activities or with sexually transmitted diseases, the diagnosis of SBF should be kept in mind.
