Although the incidence of syphilis reached a historic low in 2000, the number of incident cases has since increased in men and women across the USA. In 2019, men who have sex with men (MSM) accounted for 57% of all primary and secondary (P&S) syphilis cases, and about half of MSM with P&S syphilis are living with human immunodeficiency virus (HIV) infection. Days after infection, Treponema pallidum disseminates and invades tissues distant from the site of inoculation. Once the spirochete disseminates, the host develops an inflammatory response; diagnosis requires a high level of suspicion since syphilis may affect the skin, musculoskeletal, cardiovascular, and central nervous systems. We report a 61-year-old man with virally suppressed HIV infection who presented with polyarthralgia, chest pain, and weight loss, diagnosed with secondary syphilis, manifesting with ankle inflammatory arthritis and bone involvement, of the calvarium and manubrium. Early and late syphilis in adults can manifest with articular and periarticular pathologies, including inflammatory arthritis, tenosynovitis, periostitis, and myositis. Higher clinical suspicion is needed for prompt diagnosis of syphilis in patients who are at risk and suspected of having an autoimmune disease. This report includes a review of the musculoskeletal manifestations of syphilis. [ABSTRACT FROM AUTHOR]

The case report of a 62 years patient who was assisted in the Dermatology Service of Aquiles Espinosa Salgado Polyclinic in Las Tunas is described, who presented a 0.5 cm white lesion, of pearly aspect, in the tip of the tongue. Taking into account the characteristics of this lesion the suspected diagnosis of secondary syphilis was established. The venereal disease research laboratory test was ordered and its result was 128 dilutions, reason why an opaline syphilid was confirmed, as a manifestation of syphilis in secondary stage. The focus control was carried out and the source of infection was still without specifying. With the suitable treatment, he had a favorable clinical course, but clinical and serologic follow up was maintained as established. [ABSTRACT FROM AUTHOR]

The non-treponemal tests like VDRL and RPR hold an important place in the diagnosis of syphilis. In many countries, these tests are used for screening, with positive results being subsequently confirmed by treponemal or specific tests like TPHA or FTA-ABS. Recent observations of low-titer VDRL or RPR positivity (<1:8) or negative results in patients with clinically active syphilis are becoming a cause for concern especially in the backdrop of a resurgence of the disease. Such a scenario might undermine the usefulness of VDRL or RPR as effective screening test and for treatment monitoring. We studied the titers of non-treponemal serological test (VDRL) in non-HIV-positive, untreated cases of secondary syphilis (diagnosed clinically and confirmed serologically with specific treponemal tests like TPHA or FTA-ABS). It was an OPD-based cross-sectional study, which included patients presenting with muco-cutaneous lesions suggestive of secondary syphilis, confirmed serologically with positive specific treponemal tests, who were seronegative for HIV1 and 2 and had not received treatment with injectable benzathine penicillin. Their VDRL titers were noted. Information regarding duration of lesions and any previous genital ulcer was obtained, and additional information was sought regarding any medications taken during the last two months. Nineteen patients (12 males, 4 females, and 3 transgender individuals) between the ages of 18 and 46 years were included in the study. Ten of these cases (52.63%) had a VDRL titer of less than 1:8 (non-reactive in 5 patients, titer of 1:4 in 5 patients). Among the remaining nine cases, a titer of 1:8 was observed in six, 1: 16 in two, and 1:32 in one case. Our observations raise concerns regarding the possibility that a significant number of patients with active syphilis and potential to transmit the disease are being left untreated because of low or negative titers in the screening tests. This may account for the slow resurgence of syphilis as documented by increase in case rates and incidence of congenital syphilis in different parts of the world. [ABSTRACT FROM AUTHOR]

Background: Syphilis is a treatable bacterial infection caused by Treponema pallidum. There has been a change in incidence of syphilis in various nations over the years. Aim: To study the epidemiological trends, demographic profile, high-risk behaviour, clinical pattern, and stage of syphilis over the last ten years in patients presenting to an STD clinic in a tertiary care hospital. Material and Methods: This was a retrospective observational study over ten years. Records of all confirmed syphilis cases were analysed in relation to demography and clinical profile. Results: There were a total of 3,110 STD patients among whom 31 cases (accounting for 0.99%) of confirmed syphilis were seen. There was a significant increase in cases in the last five years of study, especially in the last year. An increase in primary (PS) and secondary syphilis (SS) was observed. Males outnumbered females (3:1). Mean age of patients was 35.0 ± 11.53 years. Professionals were most common (22.6%) having syphilis followed by farmers (19.35%). A significant proportion (45.1%) of our patients were at least graduates. Unprotected sex was seen in all the patients followed by extramarital/premarital sex (71.35%). There were 16.12% of cases who had a history of paid sex and 9.7% were homosexuals. SS and latent syphilis were more common (38.7% each) than PS (19.35%). In PS single chancre and in SS truncal asymptomatic rash was the commonest clinical presentation. Limitation: Single-centre study, including only self-reported patients leading to a small sample size, is the major limitation of the study. Conclusion: The increased trend of primary and secondary syphilis in recent years highlights that there is a risk of an impending epidemic. [ABSTRACT FROM AUTHOR]

We report two cases of secondary syphilis with an isolated papule on the palm as the initial presentation. The clinical manifestations of secondary syphilis can be diverse, with a high rate of misdiagnosis and underdiagnosis. This article presents two patients with a purpose to alert clinicians not to forget the great imitator of syphilis for lesions of uncertain diagnosis., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Syphilis is a sexually acquired disease that can affect multiple organ systems. Secondary syphilis can cause a wide range of skin manifestations, leading to misdiagnoses. Herein, we present a patient who developed a diffuse maculopapular rash concerning for a drug reaction leading to a dermatology consult. The patient was found to have secondary syphilis confirmed with immunohistochemical staining on skin biopsy tissue and a positive rapid plasma reagin. Appropriate management with benzathine penicillin G led to significant improvement in the rash. Given the increasing incidence of syphilis, increased awareness of the disease is imperative so that it can be considered in all patients given the highly variable presentation and likely confusion, at least initially, with drug reaction with eosinophilia and systemic symptoms syndrome and other drug eruptions., Competing Interests: Human subjects: Consent for treatment and open access publication was obtained or waived by all participants in this study.

Syphilis and human immunodeficiency virus (HIV) are both sexually transmitted diseases that affect the same risk group practices, which make co-infection common. Syphilis-infected individuals typically follow a disease course divided into primary, secondary, latent, and tertiary stages. Atypical manifestations, fulminant presentation, serological irregularities, and treatment failures appear more frequently in HIV-seropositive patients. We present the case of a 15-year-old boy with a penicillin allergy who developed dermatological and systemic manifestations in which laboratorial and histopathological studies corresponded to a syphilis-HIV co-infection with a positive response to treatment.

The diagnosis of syphilis can be challenging for dermatologists and dermatopathologists. In particular, secondary syphilis can have different clinical and histopathological presentations. A granulomatous tissue response is an unusual finding in secondary syphilis. We report the case of a 77-year-old man who presented with a 4-week history of non-pruritic generalised macules, papules, nodules and plaques. Histopathologically, there was a dense perivascular and periadnexal lympho-histiocytic dermal infiltrate with non-palisading and non-caseifying epithelioid granulomas and abundant plasma cells. The diagnosis of syphilis was confirmed by serology and immunohistochemical detection of Treponema pallidum in the biopsy specimen. A brief overview of the diagnostic role of immunohistochemistry is also provided, with particular emphasis on reported cases of granulomatous secondary syphilis.

Oral secondary syphilis may mimic various infectious, neoplastic, or immune-mediated processes; hence, its diagnosis may represent a challenge. Early diagnosis of syphilis, a disease that has increased in recent decades, is essential for adequate management, particularly in people living with HIV (PLWH). This study aimed to comprehensively characterize oral secondary syphilis in a group of 47 PLWH. A group of PLWH with oral secondary syphilis attending four HIV-referral centers in Mexico City was included (2004–2021). Clinical and laboratory data were retrieved, and an exhaustive oral examination was performed following the established criteria. Demographic, clinicopathological, immunohistochemical, and serological features of the patients were analyzed. Approximately 11% of PLWH with oral secondary syphilis demonstrated negative Venereal Disease Research Laboratory tests. A noticeable feature was the absence of symptoms in 95.7% of cases, despite the clinically evident appearance of the lesions. In contrast to previous results, 18% of ulcerations were detected to be deep, crateriform, and infiltrative, and 22% of the mucous patches were highly keratotic lesions. Most samples (77.3%) showed superficial lymphoplasmacytic infiltrates in the superficial lamina propria, with perivascular and perineural patterns, and immunohistochemistry was positive in 66.7% of the cases. The "great imitator" appears not only clinically but also histopathologically and immunohistochemically, where features may be comparable with those of chronic inflammatory processes, deep infections, or malignant processes. Although not recommended as a routine assay, IHC could be a critical tool, particularly in PLWH with atypical clinical features or with negative and/or dubious serology. [ABSTRACT FROM AUTHOR]

Physicians should be aware of unusual presentations of syphilis. For dermatologists, the visual recognition of lesional morphology and distribution is a fundamental part of clinical evaluation, which dictates the workup and diagnosis. Secondary syphilis has a variety of presentations, the most common being a diffuse symmetrical papulosquamous eruption. It continues to be a diagnostic challenge as the myriad manifestations of secondary syphilis can mimic many dermatological disorders. Herein we report a case of secondary syphilis with an uncommon presentation characterized by disseminated annular and arcuate lesions.

We present a woman with an unusual case of secondary syphilis after an unnoticed primary infection. She initially presented with multiple grayish plaques and nodules on the vulva associated with an erythematous macular symmetrical rash affecting the trunk and extremities. Despite the increasing incidence of sexually transmitted diseases such as syphilis, presentation with unusual manifestations can lead to a delayed diagnosis.

In immunocompromised conditions, latent syphilitic infection can lead to secondary syphilis. We present here a case of neurosyphilis(syphilitic meningomyelitis) in a kidney transplant recipient. Atypical presentation, the typical maculopapular rash, and a serological test all pointed to secondary syphilis. The scenario illustrates a crucial point: infections can go undetected, whereas a patient is on immunosuppressive therapy. [ABSTRACT FROM AUTHOR]

Background: Syphilis is one of the most serious sexually transmitted diseases worldwide, and has tremendous consequences for the mother and her developing fetus if left untreated. The burden of morbidity and mortality due to congenital syphilis is high. Purpose: Screening and prompt to know the importance of treatment of syphilis during pregnancy. Case: A 32-year-old multigravida in 5 months of pregnancy presented with multiple raised lesions over her labia. It was accompanied by fluor and smelly fishy odor. There was no history of genital ulcers in either spouse and no history of sexual promiscuity. History of antenatal care in public health showed non-reactive status of HIV, syphilis and hepatitis B. Clinical examination revealed multiple flat, moist warts over her labia mayora and minora, and multiple roseola syphilitica on the plantar pedis sinistra. Darkfield microscopic examination presence spirochete, venereal disease research laboratory (VDRL) titer was 1:16 and T. pallidum particle agglutination assay (TPHA) titer was 1:2560. Obstetric ultrasonography examination was suggestive no mayor congenital abnormalities. Both of serology VDRL and TPHA were non-reactive in her husband. Significant of lesion improvement and decrease a fourfold titer serologic in VDRL (1:4) and TPHA (1:320) as follow-up 3 months after being treated with single intra-muscular injections of benzathine penicillin 2.4 million units. Discussion: Coordinated prenatal care and treatment are vital. It’s implemented before the fourth month of pregnancy to reduce vertical transmission and all associated side effects of congenital syphilis. Penicillin is highly efficacious in maternal syphilis and prevention of congenital syphilis. Conclusion: Universal screening and adequate pregnancy care must be a priority.

Introduction: Syphilis is a chronic infection caused by Treponema pallidum. Manifestations of this disease are vast, and syphilitic hepatitis is a rarely depicted form of secondary syphilis. Case Presentation: We report the case of a 63-year-old man with worsening jaundice, maculopapular rash and perianal discomfort. Proctological examination with anoscopy revealed a perianal gray/white area with millimetric pale granules along the anal canal. Liver function tests showed a mixed pattern. Venereal Disease Research Laboratory, T. pallidum hemagglutination assay and IgM fluorescent treponemal antibody absorbance were positive. The patient was successfully treated with a single dose of penicillin G. Discussion/Conclusion: Syphilitic hepatitis is scarcely reported in the literature. Secondary syphilis with mild hepatitis rarely leads to hepatic cytolysis and jaundice. Many signs of secondary syphilis including syphilitic hepatitis may be linked to immune responses initiated during early infection. Over the past decades, evidence has emerged on the importance of innate and adaptive cellular immune responses in the immunopathogenesis of syphilis. This report raises awareness to a clinical entity that should be considered in patients at risk for sexually transmitted diseases, who present with intestinal discomfort or liver dysfunction, as it is a treatable and fully reversible condition.

Syphilis has received its classical designation as one of “the great imitators,” reflecting a wide variety of symptoms and presentations, which can cause difficulties in diagnosis. Here we report an unusual case of secondary syphilis in a person with acute necrotizing tonsillitis and Sweet syndrome. A 33-year-old female presented with fever, bilateral cervical lymphadenopathy, tonsillar enlargements with ulcerated pus-filled lesions on the right tonsil, and multiple pseudovesicular, mammillated, edematous plaques on her neck, face, and extremities. Syphilis serology was positive and a skin biopsy demonstrated a neutrophil-rich dermatitis characteristic of Sweet syndrome. The association of Treponema pallidum infection with Sweet syndrome may be a coincidence; nevertheless, our case serves as a reminder that secondary syphilis should remain in the differential diagnosis of the acute febrile neutrophilic dermatosis.

Syphilis and human immunodeficiency virus (HIV) are both sexually transmitted diseases that affect the same risk group practices, which make co-infection common. Syphilis-infected individuals typically follow a disease course divided into primary, secondary, latent, and tertiary stages. Atypical manifestations, fulminant presentation, serological irregularities, and treatment failures appear more frequently in HIV-seropositive patients. We present the case of a 15-year-old boy with a penicillin allergy who developed dermatological and systemic manifestations in which laboratorial and histopathological studies corresponded to a syphilis-HIV co-infection with a positive response to treatment.

Alopecia syphilitica (AS) is an uncommon manifestation of secondary syphilis, with a prevalence that ranges from 3% to 7%. It is a nonscarring alopecia that can present in a diffuse pattern, a moth-eaten pattern, or a mixed subtype. Due to its low prevalence and similar presentation to other forms of alopecia such as alopecia areata, telogen effluvium, and tinea capitis, dermatologists must maintain a high degree of suspicion for prompt diagnosis. The diagnosis of AS is made by eliciting the patient's history, obtaining serologic tests, and examining histopathologic or dermatoscopic findings. First-line treatment includes benzathine penicillin G injection, which leads to hair regrowth weeks to months after administration. In this article, we present a focused review on the diagnosis of AS and discuss evidence-based therapeutic approaches for the management and treatment of this condition. [ABSTRACT FROM AUTHOR]

Background: Recently, the incidence of syphilis among men who have sex with men (MSM) has increased rapidly, especially among Human Immunodeficiency Virus (HIV)-infected MSM. Coinfection with these two organisms alter the symptoms and signs, progression of the disease, and the risk of progressing to the tertiary stage. Purpose: To report a case of secondary syphilis in HIV-infected MSM. Case: A 24-year-old male complaint of multiple redness macule for 1-month duration on his chest, back, groin, palm, and soles. The rash was neither painful nor pruritic. He also complains of hair loss resulting "moth eaten" alopecia. One month before, he had a painless ulcer on his genital, which resolved without treatment. His HIV infection was diagnosed two years earlier. He had been sexually active with multiple homosexual partners without using a condom since 2010. The Venereal Disease Research Laboratory test (VDRL) titer was 1/32, and Treponema pallidum haemagglutination assay (TPHA) was 1/20480. Initial treatment was a single dose of 2.4 million units of benzathine penicillin. Serologic examination was reevaluated on month 1, 3, 6, and 9 after therapy and declined in the third month. Discussion: For HIV-infected persons, the clinical manifestations of syphilis in most of the cases remain the same. However, the lesions are more aggressive, and coexistence of primary and secondary syphilis is more frequent. Serologic tests are accurate and reliable for the diagnosis and for following a patient’s response to treatment. Penicillin is effective but physical and serological follow up is needed. Conclusion: HIV-infected MSM have higher risk of syphilis. Staging is needed to determine the treatment. Serologic examination should be repeated and long enough to monitor the treatment success.

Syphilis is a sexually transmitted infection that is undergoing a resurgence in Canada and around the world. If not diagnosed correctly, syphilis can progress to its secondary and tertiary stages, affecting numerous organ systems. We present a case of a 41-year-old female who developed a papulosquamous rash, initially diagnosed as varicella with progression to a widespread and painful rash over 3 months. Based on clinical, histological, and serological findings, she was later diagnosed with secondary syphilis and successfully treated with intramuscular penicillin. This case underscores the importance of accurate diagnosis and treatment of syphilis to prevent systemic complications. We advocate for increased awareness among frontline providers with a proactive approach to diagnosis and management, including thorough history and physical examination, low threshold for performing serological testing, biopsy for lesions that do not resolve as expected with management, and multidisciplinary involvement for complex presentations of syphilis., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2024.)

Syphilis -the "great simulator" for classical venereologists-is re-emerging in Western countries despite adequate treatment; several contributing factors have been identified, including changes in sexual behaviour, which won't be the topic of this article though. In 2021, a total of 6613 new cases of syphilis were reported in Spain, representing an incidence of 13.9×100 000 inhabitants (90.5%, men). Rates have increased progressively since 2000. The clinical presentation of syphilis is heterogeneous. Although chancroid, syphilitic roseola and syphilitic nails are typical lesions, other forms of the disease can be present such as non-ulcerative primary lesions like Follmann balanitis, chancres in the oral cavity, patchy secondary lingual lesions, or enanthema on the palate and uvula, among many others. Regarding diagnosis, molecular assays such as PCR have been replacing dark-field microscopy in ulcerative lesions while automated treponemal tests (EIA, CLIA) are being used in serological tests, along with classical tests (such as RPR and HAART) for confirmation and follow-up purposes. The interpretation of these tests should be assessed in the epidemiological and clinical context of the patient. HIV serology and STI screening should be requested for anyone with syphilis. Follow-up of patients under treatment is important to ensure healing and detect reinfection. Serological response to treatment should be assessed with the same non-treponemal test (RPR/VDRL); 3-, 6-, 12-, and 24-month follow-up is a common practice in people living with HIV (PLHIV). Sexual contacts should be assessed and treated as appropriate. Screening is advised for pregnant women within the first trimester of pregnancy. Pregnant women with an abortion after week 20 should all be tested for syphilis. The treatment of choice for all forms of syphilis, including pregnant women and PLHIV, is penicillin. Macrolides are ill-advised because of potential resistance., (Copyright © 2024 AEDV. Publicado por Elsevier España, S.L.U. All rights reserved.)

Syphilis is a sexually transmitted infection caused by the bacterium Treponema pallidum . This disease is characterized by four different stages, each presenting with a variety of manifestations or asymptomatic disease. These stages can be further broken down into early-stage syphilis, which includes primary and secondary syphilis, and late-stage syphilis, which includes tertiary syphilis. It is crucial to recognize and treat syphilis early because the later stages of the disease are marked by irreversible damage to the central nervous system (CNS) and cardiovascular system, and can even increase mortality risk. The primary recommended treatment for early-stage syphilis is intramuscular (IM) benzathine penicillin G (BPG). In this case report, we present a patient with secondary syphilis who exhibited red papules and nonspecific skin eruptions. Due to the unavailability of BPG, the patient initially received doxycycline as an alternative treatment. After eight days of searching multiple facilities and pharmacies, a dose of BPG was finally located and administered to the patient. We highlight crucial information about the BPG shortage, including supply and demand challenges, infrastructure issues, and the broader impact on numerous other antimicrobials. We emphasize the importance of recognizing this issue and provide alternatives for managing the disease in resource-limited settings., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

This paper presents a case of Moth-Eaten Alopecia as the only clinical manifestation of secondary syphilis in a 28-year-old man from Nepal. The patient exhibited progressive hair loss in the occipitoparietal region without associated pain or itching. With a positive Rapid Plasma Reagin (RPR) test (1:256), the patient received a three-week course of Benzathine Penicillin G, resulting in complete hair regrowth within four months. This case underscores the significance of recognizing moth eaten alopecia as a potential dermatological sign of secondary syphilis, especially when it appears as the sole clinical symptom.

Syphilis is an often-overlooked diagnosis and without timely diagnosis and treatment, can have serious repercussions. Although its prevalence had decreased with the introduction of penicillin, it has had a resurgence over the years. Discerning the proper patient population to test for syphilis should be led by a patient’s risk factors. Here, we present a patient diagnosed with secondary syphilis, with initial concern for a possible concomitant lupus diagnosis. He initially presented with visual symptoms and optic nerve inflammation, along with a positive antinuclear antibody (ANA). Due to an unprotected sexual encounter, there was suspicion for a sexually transmitted infection. Testing revealed reactive rapid plasma reagin (RPR) (≥1:256 titer) and reactive treponemal antibody, consistent with active syphilis. He was immediately started on intravenous Penicillin G. Lumbar puncture was consistent with a reactive venereal disease research laboratory test (VDRL). Urinalysis revealed nephrotic range proteinuria, which along with the positive ANA, prompted renal biopsy. This showed membranous nephropathy with full house staining, which is seen primarily in lupus nephritis and further confounded the diagnosis. He completed a two-week course of penicillin and steroids inpatient with clinical improvement. On follow up, his RPR improved (≥1:64 titer), and lumbar puncture showed a non-reactive VDRL. Due to the resolution of proteinuria, decrease of the ANA titer and no further positive testing or symptoms convincing for a concomitant rheumatologic disorder, the presence of lupus was collectively determined to be of low concern. and the sole diagnosis of secondary syphilis was made.

Secondary syphilis can present with wide range of mucocutaneous lesions. Because of its varied morphology, it is considered a great mimicker. However, syphilitic lesions presenting as Sweet syndrome is uncommon. We report a case of a 28 year adult male presenting with erythematous edematous papules and plaques with pseudovesicular appearance, lichenoid annular plaques on skin, and painless indurated ulcer over the glans. The Venereal Disease Research Laboratory test was reactive (1:32 dilutions), and treponema pallidum hemagglutination test was positive. The histopathology from erythematous edematous lesion and genital ulcer revealed neutrophilic abscess and characteristic plasmacytic picture in biopsy, respectively. He was treated successfully with single dose intramuscular injection of benzathin penicillin 2.4 million units. This case is reported for its rarity.

Abstract Background In Japan and other countries, the number of patients with syphilis is increasing year by year. Recently, the cases of the pulmonary involvement in patients with secondary syphilis have been reported. However, it is still undetermined how to obtain a desirable specimen for a diagnosis of the pulmonary involvement, and how to treat it if not cured. Case presentation A 34-year-old man presented with cough and swelling of the right inguinal nodes. A physical examination revealed erythematous papular rash over the palms, soles and abdomen. A 4 cm mass in the right lower lobe of the lung was detected on computed tomography. He was diagnosed as having secondary syphilis, because he was tested positive for the rapid plasma reagin and Treponema pallidum hemagglutination assay. Amoxycillin and probenecid were orally administered for 2 weeks. Subsequently, rash and serological markers were improved, however, the lung mass remained unchanged in size. Transbronchial biopsy (TBB) confirmed the pulmonary involvement of syphilis using polymerase chain reaction techniques (tpp47- and polA-PCR). Furthermore, following surgical resection revealed the lung mass to be an abscess. Conclusions To our knowledge, this is the first surgically treated case of a lung abscess caused by syphilis, which was diagnosed by PCR techniques in TBB. This report could propose a useful diagnostic method for the pulmonary involvement of syphilis.

This article discusses a case of secondary syphilis in a 22-year-old man. The patient presented with a rash on his palms and soles, as well as a genital ulceration. The diagnosis of secondary syphilis was confirmed through serological testing, and the patient was treated with prednisone and penicillin. The article emphasizes the importance of considering syphilis as a diagnosis in patients with vague lesions and highlights the usefulness of Biett's sign, a peripheral scaling around syphilis rashes, for early and accurate diagnosis. The authors of the article are Y. Zheng and M. Xu from the Department of Dermatology at Zhejiang University School of Medicine in China. [Extracted from the article]

Fever and rash as manifestations of infection by microorganisms are collectively known as febrile exanthem. Since viruses are more frequently associated with fever and rash, these symptoms are thus impetuously termed viral exanthem. However, bacteria represent a frequently overlooked infectious etiology causing rash in humans. In addition, certain microbes may exhibit pathognomonic features that erupt during illness and facilitate clinical diagnosis. Conversely, coinfections often obscure the clinical characteristics of the primary disease and further challenge clinicians attempting to reach a diagnosis. We retrospectively looked at de-identified clinical data of a patient who presented to the Hospital for Tropical Diseases in Bangkok in July 2019 with complaints of fever and rash. The case involved a 35-year-old who presented with a 3-day history of fever, respiratory symptoms, myalgia, conjunctivitis, diarrhea, and a generalized maculopapular rash. On examination, the patient was febrile, tachycardic, and tachypneic, with a mean arterial pressure of 95 mmHg. A differential white blood cell count showed: leukocytes, 5800/µL; neutrophils, 4408/µL; lymphocytes, 406/µL; and platelets, 155,000/µL. Striking findings involving the integumentary system included Koplik’s spots and generalized maculopapular rash. Further serology revealed positive immunoglobulin (Ig)M and IgG for both measles and rubella virus, including reactive serology for Treponema pallidum. Here we describe the clinical course and management of this patient.

Syphilis is considered one of the greatest imitators which can mimic any skin disease. Keen examination together with a sound brain and a high degree of suspicion is required for its diagnosis. Syphilis, a sexually transmitted disease caused by spirochete Treponema pallidum pallidum, was more common during the Second World War. Later, as the human immunodeficiency virus cases increased, there was increased,incidence of all sexually transmitted diseases including syphilis as they facilitate transmission of each other. Syphilis manifests with cutaneous as well as systemic features and is divided into several stages (primary, secondary, latent, and tertiary), with different signs and symptoms associated with each stage. In this article, we report an unusual case of secondary syphilis from Saudi Arabia manifesting with palmar rash without any systemic manifestations. [ABSTRACT FROM AUTHOR]

A 20-year-old young woman with cauliflower-shaped lesions on her vulva was misdiagnosed as condyloma acuminatum. Further evaluation revealed positive serological tests for syphilis. On histological examination, and numerous plasma cells were seen to infiltrate the dermis heavily. The cauliflower-shaped lesions on vulva completely disappeared after benzathine penicillin treatment. Cauliflower-shaped lesions are a rare manifestation of secondary syphilis.

ABSTRACT It is essential for health care providers to be familiared with the full spectrum of clinical presentations of syphilis. We present herein a case of syphilide psoriasiforme, an uncommon but well recognized clinical presentation of secondary syphilis. A 46-year-old HIV-infected female patient was referred to our attention with a presumptive diagnosis of palmoplantar psoriasis. On examination, there were exuberant pinkish-red papules and plaques covered with a thick silvery scale in the palms, flexor surfaces of the wrists, and the medial longitudinal arches of the feet. Serological and histopathological analyses uncovered the diagnosis of syphilis. Clinical remission was obtained after treatment. A detailed review of the literature on syphilide psoriasiforme, including descriptions from older syphilology textsis provided. The present case report emphasizes the need for clinicians to have a heightened awareness of the varied and unusual clinical phenotypes of syphilis.

Secondary syphilis represents a diagnostic challenge due to its varied clinical manifestations. Co-infection with human immunodeficiency virus (HIV) adds to the diversity of the clinical presentation of syphilis. We herein report a case of secondary syphilis as an arthropod bite-like eruption in a previously undiagnosed HIV-coinfected patient. A 24-year-old homosexual male presented with multiple corticosteroid-resistant insect bite-like nodules on his trunk and bilateral arms. Skin biopsy disclosed plasma cell infiltration and positive Treponema pallidum staining. His symptoms got dramatic remission after benzathine penicillin G therapy. The presented case extends the clinical spectrum of secondary syphilis in HIV patient.

Abstract Background Treponema Pallidum (TP), the pathogen of syphilis, commonly infects bones in cases of congenital and tertiary syphilis, but it is rare in the primary and secondary stages. With its mild symptoms and rare clinical findings, it might be easy to dismiss the diagnosis of early syphilis. Usually, effective results can be achieved after the conventional strategy of antibiotic treatments, mainly penicillin. To our knowledge, our case is so far the most serious reported case of destructive bone lesion in secondary syphilis, and our treatment for the case is the first strategy using total hip arthroplasty in secondary syphilis. Case presentation We present the case of a 71-year-old man with local repeated pain and dysfunction in the right hip. Radiologic examinations showed the disappearance of the ipsilateral femoral head and neck. After excluding the aetiologies of cancer metastasis and tuberculosis, we confirmed the diagnosis of syphilitic arthritis. The patient received the medical treatment of antibiotics and the surgical treatment of total hip arthroplasty. At the follow-up of 1, 3, and 5.5 years after the operation, the patient presented with a pain-free and functional hip prosthesis without local signs of infection and loosening. Conclusions This report highlights the difficulties of early diagnosis of secondary syphilis with bone involvement. Bone defect of the femur with secondary syphilis, especially at the proximal femur, was an extremely rare complication in the previous reports. Our case was the first case of a patient who experienced the disappearance of femoral head and neck caused by secondary syphilis. Follow-up after the operation proved the successful treatment of the extensive bone defect of femur by total hip arthroplasty.

A 46-year-old woman presented with slightly itching, painless erythematous nodules on the face, neck, and genital area. Initial differential diagnoses included cutaneous lymphoma. We performed punch biopsy on her neck. In histopathology, interface dermatitis with some nodular infiltration of numerous neutrophils and plasma cells was observed, therefore, serologic tests for syphilis were performed. Owing to positive serologic test results and dramatically improved skin lesions after treatment with benzathine penicillin, nodular secondary syphilis was diagnosed. Nodular skin lesions in secondary syphilis are uncommon and often misleading. Our case suggests secondary syphilis should be considered in the differential diagnosis of nodular lesions.

Syphilis is a sexual transmitted disease caused by Treponema pallidum and an underdiagnosed and underreported cause of acute hepatitis. In recent years, reported cases of primary and secondary syphilis have been increasing, mostly in men who have sex with men. Clinical manifestations of syphilis are diverse, earning the name of "the great imitator" which can affect virtually any organ. Nonetheless, hepatic involvement is rare, but it can occur at any stage of the disease. We present the case of a 41-year-old immunocompetent male, that presents to us with a cholestatic hepatitis and a diffuse erythematous rash with palmo-plantar affection. The patient had no history of primary syphilis. After throughout aetiologic study, he was diagnosed with syphilitic hepatitis and treated with intramuscular Benzathine benzylpenicillin, with the disappearance of the rash and normalization of liver enzymes after 3 months. We would like to highlight that this aetiology should be considered in patients with unexplained elevation of liver enzymes (mainly cholestatic enzymes) and an epidemiologic context of unsafe sexual exposure.

Syphilis has received its classical designation as one of "the great imitators," reflecting a wide variety of symptoms and presentations, which can cause difficulties in diagnosis. Here we report an unusual case of secondary syphilis in a person with acute necrotizing tonsillitis and Sweet syndrome. A 33-year-old female presented with fever, bilateral cervical lymphadenopathy, tonsillar enlargements with ulcerated pus-filled lesions on the right tonsil, and multiple pseudovesicular, mammillated, edematous plaques on her neck, face, and extremities. Syphilis serology was positive and a skin biopsy demonstrated a neutrophil-rich dermatitis characteristic of Sweet syndrome. The association of Treponema pallidum infection with Sweet syndrome may be a coincidence; nevertheless, our case serves as a reminder that secondary syphilis should remain in the differential diagnosis of the acute febrile neutrophilic dermatosis.

Syphilis is one of the sexually transmitted infections caused by Treponema pallidum, having clinical features that vary depending on its stage. Early stage consists of primary, secondary, and early late syphilis, whereas advanced stage consists of late latent and tertiary syphilis. The serological examination of syphilis is used for presumptive diagnosis. Venereal disease research and laboratory (VDRL) test and treponema pallidum hemagglutination assay (TPHA) are among the serological tests that are easy to conduct and inexpensive. Proper diagnosis and treatment are necessary not only to reduce transmission rates but also to avoid complications that occur in the advance stage of this disease because no single typical dermatological clinical features are present at this stage. Follow-up and response to treatment should be considered. By comparing the post-treatment VDRL titer with the titer at the start of treatment, a serologic response after treatment may be evaluated, whether the patient is cured or not. Here, a case of a 55 year-old man who suffered from secondary syphilis is reported based on anamnesis, physical examination, and investigation of VDRL and TPHA. The patient was treated with benzathine penicillin with a single dose of 2.4 million UI intramuscularly and provided a good clinical response. On VDRL clinical and laboratory evaluations after 9 months of treatment, there was significant progress, meaning the treatment was success. [ABSTRACT FROM AUTHOR]
