Lues maligna in early HIV infection case report and review of the literature

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.

Malignant syphilis as the presenting complaint of advanced HIV

Malignant syphilis is an infrequent secondary manifestation in patients with human immunodeficiency virus (HIV), with polymorphous and disseminated skin lesions being related to severe immunosuppression. Lesions have intense inflammatory circinate, ulcer-crusted and nodular skin lesions of diffuse distribution throughout the body, that can be confused with vasculitis or cutaneous lymphomas. We report a patient recently diagnosed with HIV infection in the acquired immunodeficiency syndrome stage with malignant syphilis as the debut of HIV.

Case report of a man with HIV presenting with malignant syphilis

BACKGROUND

Malignant syphilis is a rare manifestation of secondary syphilis and is commonly associated with human immunodeficiency virus coinfection. It can present with multiorgan involvement, which poses a diagnostic dilemma to clinicians.

METHODS

We report a case of a middle aged male who presented with near complete vision loss in his right eye with initial concern for fungal endophthalmitis due to his injecting drug use history. He concurrently had right cheek and forearm ulcerative plaques.

RESULTS

He was diagnosed with disseminated syphilis following the punch biopsy of his right cheek, with positive Treponema pallidum result on polymerase chain reaction and identification of spirochaetes on immunostaining from histopathology.

CONCLUSIONS

We present the epidemiology of syphilis in Australia and highlight the importance of testing for common sexually transmitted diseases within the emergence of the monkeypox outbreak.

Syphilis in Dermatology: Recognition and Management

The incidence of syphilis has been increasing in the USA since 2000. Notably, the coronavirus disease 2019 pandemic negatively impacted the public health efforts to contain the spread of sexually transmitted diseases including syphilis and congenital syphilis. Clinical manifestations of syphilis are predominantly mucocutaneous lesions, thus dermatologists are primed to recognize the myriad presentations of this disease. Primary syphilis is classically characterized by a painless transient chancre most often located in the genital area. Secondary syphilis typically manifests clinically as systemic symptoms in addition to a mucocutaneous eruption of which a variety of forms exist. Although less common in the era of effective penicillin treatment, late clinical manifestations of syphilis are described as well. In addition to recognition of syphilis on physical examination, several diagnostic tools may be used to confirm infection. Treponema pallidum spirochetes may be detected directly using histopathologic staining, darkfield microscopy, direct fluorescent antibody, and polymerase chain reaction assays. A table detailing the histopathologic features of syphilis is included in this article. Serologic testing, non-treponemal and treponemal tests, is the preferred method for screening and diagnosing syphilis infections. Two serologic testing algorithms exist to aid clinicians in diagnosing positive syphilis infection. Determining the correct stage of syphilis infection combines results of serologic tests, patient history, and physical examination findings. Using the current Centers for Disease Control and Prevention case definitions and treatment guidelines, a management algorithm is proposed here. Penicillin remains the pharmacological treatment of choice although specific clinical situations allow for alternative therapies. Syphilis is a reportable disease in every state and should be reported by stage according to individual state requirements. Screening recommendations are largely based upon risks encountered through sexual exposures. Likewise, sexual partner management includes evaluating and treating persons exposed to someone diagnosed with an infective stage of syphilis. Close clinical follow-up and repeat testing are recommended to ensure appropriate response to treatment. This guide will discuss the current epidemiology of syphilis and focus on practice aspects of diagnosis and management, including public health reporting.

Malignant Syphilis: A Systematic Review of the Case Reports Published in 2014-2018

Malignant syphilis (MS) is a rare manifestation of secondary syphilis which mainly occurs in immunocompromised individuals such as those coinfected with human immunodeficiency virus (HIV). However, recent reports have described MS in immunocompetent individuals. To describe the characteristics of individuals with MS and associated risk factors, a review of case reports published from 2014 to 2018 was conducted. Out of 45 published case reports, 33 cases (73%) occurred in HIV-positive individuals with majority having CD4 counts <500 cells/mm3. Of the 12 cases (27%) in HIV-negative individuals, half had comorbidities such as diabetes mellitus, alcoholism, drug abuse, psoriasis, and hepatitis. The most frequent manifestation of MS was ulceronodular cutaneous lesions with central adherent crust, which affected the face, trunk, and limbs. Given the increasing number of MS regardless of the immune status, dermatologists and general practitioners should be vigilant to allow early diagnosis and treatment, hence reducing their morbidity.

An AIDS Patient with Recurrent Multiple Skin Crusted Ulcerations

Malignant syphilis is considered a rare disease, more commonly affecting individuals with poor immunity. We report a case of acquired immune deficiency syndrome (AIDS) with repeated crusted ulcerations. Our report shows the typical skin lesions of malignant syphilis and a reinfection with the same rashes. A 22-year-old homosexual male was admitted to hospital for fever and ulcerations with overlying brown-black rupioid crusts. Then he was confirmed human immunodeficiency virus infection. Malignant syphilis was diagnosed by positive markers and biopsy pathology. After application of benzathine penicillin for 3 weeks, the symptoms improved and rapid plasma regain (RPR) decreased from 1:64 to 1:4 in 8 months. But the patient appeared with rashes that was accurately the same with rashes before 13 months later, and RPR rose to 1:128, which was likely to be reinfection after frequent sexual activity. And he responded well to doxycycline treatment. Although the clinical manifestations of malignant syphilis are severe, the response to the therapy of penicillin and doxycycline are excellent, even with repeated infection.

A rare case of malignant syphilis after adalimumab therapy due to Crohn's disease associated with bariatric surgery

Malignant syphilis (also known lues maligna) is a rare and severe variant of secondary syphilis. It is most commonly seen in patients who are infected with human immunodeficiency virus (HIV), and rarely, it can occur in immunocompetent individuals. The exact mechanism of the development of malignant syphilis is not clear. It could probably be associated with immunosuppression, inappropriate immune response of the host, or virulent strain of Treponema pallidum. Coexistence of immunosuppression and inappropriate immune response may predispose to develop malignant syphilis in HIV-infected patients with immune reconstitution inflammatory syndrome. Herein, we report the first case of malignant syphilis after adalimumab therapy for Crohn's disease due to bariatric surgery and discuss the underlying possible pathogenic mechanisms.

Neurosyphilis is more common in malignant syphilis: A case series and review of the literature

Malignant syphilis is a rare skin manifestation of secondary syphilis, which has been reported primarily in the HIV-infected population. This study aimed to investigate the relationship between HIV infection, malignant syphilis, and neurosyphilis through a systematic chart review of 26 malignant syphilis patients seen at our hospital. We also performed a literature review of 83 reported malignant syphilis cases since 1987, when the first case of malignant syphilis co-infected with HIV was reported. We found there was no direct association between HIV infection and malignant syphilis or neurosyphilis. In contrast, we found that much higher proportion (30%) of malignant syphilis patients develop concurrent neurosyphilis compared to those with the common type of secondary syphilis (13.1%). Physicians should be aware of the fact that neurosyphilis is more common among patients with malignant syphilis and the importance of investigating for neurosyphilis in such patients.

Sexually acquired syphilis: Historical aspects, microbiology, epidemiology, and clinical manifestations

Syphilis is caused by infection with the spirochetal bacterium Treponema pallidum subsp. pallidum. It was first recognized in the late 15th century. Since 2000, the incidence of sexually acquired syphilis has increased substantially in the developed world, with men who have sex with men and persons living with HIV infection disproportionately affected. Clinical manifestations of syphilis are protean and often include mucocutaneous manifestations. The first article in this continuing medical education series reviews historical aspects, microbiology, epidemiology, and clinical manifestations of sexually acquired syphilis.

Syphilis Maligna: A Presentation to Bear in Mind

Malignant syphilis is an uncommon form of secondary syphilis associated with HIV infection. Clinically, it is characterized by necrotic nodules and generalized ulcerated lesions. We present 4 cases of malignant syphilis diagnosed after evaluating syphilis cases diagnosed at our hospital between 2012 and 2016. We describe the epidemiologic, clinical, histiopathologic, and serologic characteristics of malignant syphilis and explore its response to treatment and association with HIV infection. Although malignant syphilis is uncommon, there has been an increase in the number of cases published in recent years, particularly in young HIV-positive patients. Malignant syphilis must be contemplated in the differential diagnosis of HIV patients with ulcerated, necrotic lesions.

Lues Maligna as an Initial Presentation of Underlying HIV Infection in a Homosexual Man

Lues maligna is a rare ulcerative form of secondary syphilis. This clinical entity is predominantly found in patients living with HIV or AIDS. We report a case of a 32-year-old homosexual man with diffuse non-pruritic, papular skin lesions, ulcerated nodules and plaques disseminated on the face, trunk and extremities. The rash was followed by fever, malaise and joint pains. Serological tests for syphilis were positive. The patient was treated with intramuscular penicillin and the lesions resolved completely. Lues maligna was an initial presentation of underlying HIV infection. The HIV seropositivity was confirmed by Western blot analysis. Due to the increased number of syphilis cases and frequent HIV co-infection in Serbia, dermatologists must be able to recognize this condition based on clinical characteristics and risk factors and to diagnose and treat it promptly.

Syphilis the great pretender: when is cancer not cancer?

The number of cases of syphilis continues to rise in the UK, USA and elsewhere and may present to a variety of clinical specialties. We report a complex case of early acquired disseminated syphilis causing an ulceronodular rash (lues maligna), orchitis, osteitis and lung nodules in an immunocompetent man who has sex with men who presented to the genitourinary medicine clinic. Syphilis should be considered in the differential diagnoses of multiple clinical presentations and optimal management should involve multidisciplinary care.

The great impostor: Lues maligna in an HIV-infected male

Lues maligna is a rare severe cutaneous manifestation of secondary syphilis. It is also known as malignant syphilis and ulceronodular syphilis. We report a case of a 58-year-old HIV-infected male who presented with diffuse, pruritic, non-tender, maculo-papular skin lesions, ulcerated nodules and plaques surrounded by an erythematous base. The disseminated skin lesions were at various stages and were located on his back, chest, arms and testicles. Patient had been receiving antiretroviral therapy. Laboratory studies had demonstrated CD4 lymphocyte count of 463 cells/mm³ and an undetectable HIV viral load. Workup revealed a rapid plasma reagin of 1:256 dilutions and the skin biopsy findings were compatible with syphilis. The skin lesions resolved with intramuscular penicillin. We herein describe a rare case of lues maligna in an HIV-infected patient with a preserved immune function and viral suppression. Such skin lesions can mimic fungal or mycobacterial infections and can pose a diagnostic challenge. Even in the modern era, syphilis remains the great impostor. Clinicians must be able to recognize this condition based on clinical characteristics and risk factors to diagnose and treat this condition promptly.

A nodular-ulcerative form of secondary syphilis in AIDS

An uncommon variant in the pre-AIDS era, lues maligna is a nodular-ulcerative form of secondary syphilis. We present a case of a 41-year-old man with HIV infection who developed fever, chills, nausea, vomiting, right upper quadrant abdominal pain, weight loss, watery diarrhea, and a painless, nonpruritic rash. He had diffuse nodular-ulcerative lesions in various stages of development. He was found to have a CD4 count of 101 cells/mm3 (22%), an HIV viral load of 2,735,060 copies/mL, and a positive rapid plasma reagin at 1:64. He was started on emtricitabine, tenofovir, and dolutegravir, as well as doxycycline. He was given benzathine penicillin 2.4 million units intramuscularly and within hours developed a Jarisch-Herxheimer reaction. Skin lesions showed signs of healing, and constitutional symptoms improved 48 hours later.

Case report of three consecutive lues maligna infections in an HIV-infected patient

Lues maligna is a rare presentation of an infection with Treponema pallidum. Here we report three lues maligna infections with severe dermatological manifestations in a single HIV-1 infected individual. Despite the start of highly active antiretroviral therapy and a substantial increase in CD4 cell count after the first episode, he developed consecutive episodes. We assume a specific immunological predisposition to react to T. pallidum in this patient.

Return of the Great Pox

Syphilis is on the increase globally. While recognized more frequently in patients with, HIV/AIDS, it is not unusual among immune competent individuals sometimes presenting with unusual manifestations and/or behaviour. This paper reviews the history and clinical features of syphilis and draws attention to the oral manifestations. CPD/Clinical Relevance: Syphilis should be in the differential diagnosis of oral ulcers or unusual oral lesions.

Malignant syphilis in an immunocompetent female patient

Malignant syphilis is an uncommon manifestation of secondary syphilis, in which necrotic lesions may be associated with systemic signs and symptoms. Generally it occurs in an immunosuppressed patient, mainly HIV-infected, but might be observed on those who have normal immune response. Since there is an exponential increase in the number of syphilis cases, more diagnoses of malignant syphilis must be expected. We report a case in an immunocompetent female patient.

Malignant syphilis in an AIDS patient

Malignant syphilis is an uncommon, but not unknown, ulcerative variation of secondary syphilis. The lesions typically begin as papules, which quickly evolve to pustules and then to ulcers with elevated edges and central necrosis. It is usually, but not mandatory, found in patients with some level of immunosuppression, such as HIV patients, when the TCD4(+) cell count is >200 cells/mm(3). Despite the anxiety the lesions cause, this form of the disease has a good prognosis. The general symptoms disappear right after the beginning of treatment, and lesions disappear over a variable period. This study reports the case of a 27-year-old man who has been HIV positive for 6 years, uses antiretroviral therapy incorrectly, has a TCD4(+) cell count of 340 cells/mm(3), a VDRL of 1:128 and itchy disseminated hyperchromic maculopapular lesions with rupioid crusts compatible with malignant syphilis.

Malignant syphilis as the first manifestation of HIV infection

Malignant syphilis is a rare and severe variant of secondary syphilis. It is clinically characterized by large papular, nodular and ulcerative lesions affecting the trunk and the extremities and covered with thick crust. We present a case of 52-year-old homosexual male who developed malignant syphilis and this was the first clinical manifestation of HIV infection. The patient was treated successfully with intravenous aqueous crystalline penicillin G. Physicians should recognize malignant syphilis and consider it in all HIV-infected individuals with ulceronodular skin lesions.

Malignant syphilis with ocular involvement in an HIV-infected patient

Malignant syphilis is now considered a rare disease, more commonly affecting individuals with poor health, malnutrition or HIV infection. We present a 34-year-old man with HIV infection who developed multiple atypical cutaneous ulcerations, leonine facies, a scleral nodule and keratitis with visual loss. The diagnosis of malignant syphilis was delayed due to the insidious presentation, but was confirmed via immunohistochemical (IHC) staining with anti-Treponema antibodies of a skin biopsy. Significant clinical improvement was observed following a 15-day course of penicillin and tigecycline therapy. In advanced HIV disease, cutaneous manifestations are often difficult to identify and present a challenge for the clinician. Clinical manifestations of secondary syphilis vary greatly, earning the epigram of 'the great imitator'. It is important to recognize atypical presentations of syphilis, especially among HIV-infected individuals. Unlike historical cases of malignant syphilis, Treponema pallidum was found in the tissue section using IHC staining methods. We emphasize the importance of lues maligna in the differential diagnosis of HIV-infected patients with diffuse ulceronodular lesions as well as the usefulness of histological investigations and IHC studies.

Ulceronodular syphilis (lues maligna praecox) in a person newly diagnosed with HIV infection

In this case of secondary syphilis, pustular lesions progressed rapidly to painful ulcerative lesions in a patient with early HIV infection. This rapidly progressive form of early syphilis has historically been called lues maligna praecox, a severe form of noduloulcerative secondary syphilis. Serologic tests for syphilis were positive and biopsy showed forms consistent with Treponema pallidum in the lesions. This case demonstrates how HIV infection may affect presentation and diagnosis of secondary syphilis.

Skin infections in HIV-infected individuals in the era of HAART

PURPOSE OF REVIEW

Clinicians should be aware of the shift in the cutaneous infectious disease burden in human immunodeficiency virus-infected individuals as a reflection of immune restoration in the era of highly active antiretroviral therapy (HAART).

RECENT FINDINGS

As in the general population but to greater extent, methicillin-resistant Staphylococcus aureus (MRSA) soft-tissue infection is a rising problem among those with human immunodeficiency virus (HIV). Human papilloma virus (HPV) is exceedingly prevalent and persistent despite HAART, and HPV-associated malignancy is increasing as those with HIV live longer. Herpes, syphilis, and Kaposi's sarcoma continue to plague individuals with HIV. Immune reconstitution inflammatory syndrome (IRIS) is common and often presents with infectious cutaneous manifestations.

SUMMARY

This review implicates the importance of the acknowledgment of MRSA infections risk factors, screening for HPV-related neoplasia, continuance of trials to establish the efficacy of herpes vaccines, and awareness of prevalent cutaneous infections presenting with IRIS in those with HIV.

Pathologically confirmed malignant syphilis in an HIV-infected patient

We report a case of pathologically confirmed malignant syphilis in an HIV-infected patient. Physical examinations revealed ulceronecrotic skin lesions. Skin biopsies demonstrated syphilis spirochetes on immunohistochemical stain, and syphilis serological titers were positive. Treatment with intravenous penicillin G was begun, and complete resolution of the skin lesions was observed. A rapid plasma reagin titer test performed 3 months after treatment revealed a 4-fold reduction in the titer, indicating successful treatment.
