Annular and arciform lesions of the palms as unique manifestations of secondary syphilis.

We describe a patient presenting with annular-arciform symmetric lesions of the palms as the unique manifestation of secondary syphilis. The polymorphism of skin lesions in secondary syphilis depends entirely on the degree of inflammatory infiltrate, the level of vascular involvement and the resulting ischemia of the skin. Besides the transient and diffuse maculo-papules (roseola syphilitica), secondary syphilis skin lesions may have different morphology and shape. It has already been reported that in cases of reinfections by Treponema pallidum the skin lesions may be arciform, as in our patient, and asymmetric. Indeed, previous syphilis may attenuate the clinical and laboratory manifestations of a new infection with T.pallidum, that occurs with less severe skin manifestations or presents as latent syphilis. However, to our knowledge, annular-arciform lesions of the palms as unique manifestations of secondary syphilis have never been described. Clinicians should be well trained to recognize the atypical presentations of syphilis, especially in patients who have already received a syphilis diagnosis, since its incidence is steadily increasing in Europe, especially in men having sex with men.

Syphilis: A Contemporary Clinicopathologic Assessment.

Syphilis is a sexually transmitted disease caused by the spirochetal bacterium Treponema pallidum that has been of public health concern for centuries. In the United States, it is currently a reportable disease and one which is recently generating increasing case numbers especially in at risk populations of immune deficiency and men who have sex with men. The present series examines biopsies from 13 patients collected over a 12-year period from a general hospital network in north suburban Cook County, Illinois. There were 13 patients (11 male: 2 female) with varied presentations, including primary ulcerated anogenital chancres, mucosal lesions, peculiar rashes, and alopecia. The reason(s) for biopsy were not clear from the clinical record, as a clinical consideration of syphilis was recorded in only 3 cases. Histologic examination of the mucocutaneous lesions encompassed a spectrum of findings including ulceration, psoriasiform hyperplasia, intense mixed band-like inflammation at the dermal-epidermal junction with a prominent plasma cell component. The contemporary availability of an effective immunostain is a valuable diagnostic adjunct. The organisms generally parallel the intensity of the inflammatory infiltrate but the distribution may vary and rarely, organisms may be absent despite serologic confirmation. Previous corkscrew morphology of the organism described ultrastructurally is reflected in the immunostained representation. Although the diagnosis of syphilis remains a clinical one in most cases, some patients will have unusual presentations and biopsies will be done. The awareness of the pathologist will facilitate prompt and effective treatment.

A Young Boy with Persistent Nodules and Hoarseness: A Rare Presentation of Nodular Secondary Syphilis.

Syphilis is a venereal disease caused by treponema pallidum, historically known as "great mimicker" because of its variable presentations. Secondary syphilis usually presents with maculopapular or papulosquamous rash. Rare manifestations include papulonodular, annular and lichenoid lesions. Nodules are usually found in benign tertiary syphilis. We present a case of a young boy who presented with five months' history of nodular skin lesions and hoarseness of voice. Venereal disease research laboratory (VDRL) was initially negative owing to prozone phenomenon. However, histopathology was confirmatory and he responded to benzathine penicillin. We present this case because of rare clinical presentation with persistent nodular lesions, unusual age group, and negative initial VDRL test.

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.

Human immunodeficiency virus-positive secondary syphilis mimicking cutaneous T-cell lymphoma.

Malignant syphilis or lues maligna is a severe form of secondary syphilis that was commonly reported in the pre-antibiotic era, and has now reemerged with the advent of the human immunodeficiency virus (HIV) epidemic. However, the characteristic histopathological findings of malignant syphilis remain controversial. The aim of this case report was to clarify the clinical and histopathological findings of HIV-positive malignant secondary syphilis. A Japanese man in his forties complained of fever, skin lesions, headache, and myalgia without lymphadenopathy during the previous 4 weeks. The skin lesions manifested as erythematous, nonhealing, ulcerated papules scattered on his trunk, extremities, palm, and face. Although the skin lesions were suspected to be cutaneous T-cell lymphomas on histological analyses, they lacked T-cell receptor Jγ rearrangement; moreover, immunohistochemical analyses confirmed the presence of spirochetes. The patient was administered antibiotics and anti-retroviral therapy, which dramatically improved the symptoms. On the basis of these observations of the skin lesions, we finally diagnosed the patient with HIV-associated secondary syphilis that mimicked cutaneous T-cell lymphoma. The patient's systemic CD4+ lymphocyte count was very low, and the infiltrate was almost exclusively composed of CD8+ atypical lymphocytes; therefore, the condition was easily misdiagnosed as cutaneous lymphoma. Although the abundance of plasma cells is a good indicator of malignant syphilis on skin histological analyses, in some cases, the plasma cell count may be very low. Therefore, a diagnosis of malignant secondary syphilis should be considered before making a diagnosis of primary cutaneous peripheral T-cell lymphoma or lymphoma associated with HIV infection.

The great imitator revisited: the spectrum of atypical cutaneous manifestations of secondary syphilis.

Syphilis is a well-known sexually transmitted infection infamous for its protean cutaneous manifestations. Over the last decade, the rate of infection in the USA has risen, particularly among human immunodeficiency virus (HIV)-infected individuals and certain ethnic groups. Although the primary chancre developing at the site of inoculation usually has typical and well-characterized features, cutaneous manifestations of secondary syphilis span a wide spectrum and mimic those of other dermatoses. This may be particularly evident in patients with HIV. Such deviations from the expected typical papulosquamous eruption may present a diagnostic challenge and delay diagnosis and therapy. Given the increasing incidence of syphilis among the immunosuppressed patient population, recognition of atypical cutaneous manifestations is critical for adequate management. We review a range of cutaneous manifestations of secondary syphilis and the skin diseases it may mimic.
