Malignant syphilis in an HIV-infected patient

Patients with HIV infection may develop common diseases with atypical clinical features. HIV infection may change the classic clinical course of syphilis and increase the incidence of a subtype of secondary syphilis named malignant syphilis. A homosexual patient with HIV infection consulted us about a one-month history of general malaise and widespread cutaneous ulcerative lesions, some with thick hemorrhagic crusts. Serology for syphilis was positive at high titers. Based on clinical, histological and serological findings, a diagnosis of malignant syphilis was made and the patient started treatment with penicillin G benzathine with progressive resolution of lesions. Malignant syphilis is a rare subtype of secondary syphilis that presents special clinical and histological features and has been associated with several processes characterized by variable degrees of immunosuppression. It is necessary to take into account this entity among the possible diagnoses in HIV-infected patients with cutaneous lesions.     

Sweet syndrome associated with secondary nodular syphilis in an immunocompetent patient

Sweet syndrome is an inflammatory disease characterized by fever, neutrophilia, papules and erythematous plaques, and a skin neutrophilic infiltrate. Syphilis has been reported among the infectious causes of Sweet syndrome. Syphilis can present atypical manifestations; a rare presentation is nodular syphilis, characterized by nodules with granulomas and plasma cells at histopathology. This case report presents a 20-year-old woman patient, with plaques and nodules, and systemic symptoms. The histopathological exam revealed both non-tuberculoid granulomas and a dense infiltration of polymorphonuclear neutrophils in the dermis. These findings, plus laboratory abnormalities, characteristic of both conditions, were conclusive for Sweet syndrome and nodular syphilis association.     

Management of syphilis in the HIV-infected patient: Facts and controversies

After reaching an all time low at the turn of the millennium in several industrialized countries, the syphilis incidence is rising again, perhaps as a consequence of unsafe sexual behavior in response to improved antiretroviral therapeutic options for HIV. Since the beginning of the HIV pandemic, numerous reports on the various aspects of the interaction between syphilis and HIV have been published. Controversies persist on many issues of the management of coinfected patients. This contribution presents a critical appraisal of the available literature. Few large-scale, properly designed, controlled studies have compared syphilis baseline presentation and treatment response according to HIV status. Among the weakness are (1) high rates of patients lost to follow-up, (2) lack of long-term follow-up, (3) lack of gold standard criteria for treatment response, (4) small sample size, and (5) lack of stratification according to syphilis stage, ongoing antiretroviral treatment, CD4 cell count and HIV viral load. From the available data, and given the ever-possible publication bias, we conclude that if HIV has an effect on the course of syphilis, it is small and clinically manageable in most cases. The controversial issues discussed should furnish the rational for clinical research during the forthcoming decade.     

Solitary oral condylomata lata in a patient with secondary syphilis

A case report of a patient with oral condylomata lata is presented. Physical examination showed that the lesions were the only symptom of secondary syphilis. The diagnosis was based on dark-field microscopy of specimens from the lesions and serologic tests for syphilis. The condylomata lata responded well to treatment of the syphilis with procaine penicillin G.     

Condyloma latum mimicking keratoacanthoma in patient with secondary syphilis.

A 31 year old man with a condyloma latum simulating a keratoacanthoma at the umbilicus is reported. The umbilicus should be included in the list of known sites of predilection for condylomata lata.     

Papulonodular secondary syphilis in a 52-year-old non-HIV heterosexual patient

There has been a recent increase in the incidence of syphilis in Slovenia, similar to other countries. Secondary syphilis can manifest with various clinical and histopathological presentations. We report the case of a 52-year-old patient that presented with nonpruritic nodular lesions on the face, trunk, and insteps that clinically mimicked lymphoma or sarcoidosis. Histopathological findings showed granulomatous inflammation. The serology revealed positive non-treponemal and treponemal tests. Treatment with benzathine penicillin G was successful.     

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.
