Condyloma lata of the umbilicus: A case report highlighting the present syphilis emergency.

Syphilis is an ancient sexually transmitted infection that plagues communities across the United States and the world. Cutaneous syphilis has a wide variety of manifestations and presentations, and is notoriously difficult to identify clinically as a result. In this report, we describe the case of a 30-year-old patient with condyloma lata on the umbilicus, an extremely rare site for the presentation of these lesions. With the recent surge in syphilis infections nationwide, including congenital infections, this case underscores the urgent necessity for heightened syphilis awareness and suspicion among clinicians.

Pemphigus syphiliticus with Jarisch-Herxheimer reaction in a newborn.

Congenital syphilis is a serious, disabling, and life-threatening infection that is transmitted transplacentally from mother to fetus. Early diagnosis is often difficult because affected infants are usually asymptomatic at birth and clinical findings are often subtle and nonspecific. Pemphigus syphiliticus is an early presentation of congenital syphilis which is characterized by fluid-filled vesicles and bullae which appear mostly on the extremities and tend to rapidly desquamate and erode. Awareness of the clinicians to this early cutaneous manifestation and possible treatment reaction will allow for prompt diagnosis and adequate treatment of syphilis-infected patients.

Round Bodies Detected by Treponema pallidum Immunohistochemical Stain in Two Cases of Cutaneous Syphilitic Gummata.

ABSTRACT: Tertiary syphilis may present a diagnostic challenge due to negative nontreponemal serologies in up to 30% of cases and frequent lack of identifiable spirochetes on histopathology or other direct detection tests. We report 2 cases of round bodies staining with Treponema pallidum immunohistochemistry by light microscopy in biopsies from cutaneous syphilitic gummata. In 1 case, the finding was validated 3 times by 2 independent laboratories; in the other case, T. pallidum was detected by polymerase chain reaction in the biopsy sample. Spirochete round bodies have previously been reported in the setting of electron microscopy and fluorography, but to the best of our knowledge, have not been reported by light microscopy in a routine skin biopsy. Although the clinical implications are unclear, this may represent a helpful new paradigm for the diagnosis of tertiary syphilis.

Rare Presentation of Umbilical Condyloma.

Syphilis is associated with 3 stages of infection-primary, secondary, and tertiary-each with their own associated clinical findings. Secondary syphilis manifests with condyloma lata and other cutaneous findings, and typically occurs several months after the initial infection. Condyloma lata are primarily found in the genital area, but may also be found in other locations such as the umbilicus, axilla, and neck. This brief report describes an umbilical condyloma lata discovered in a patient with secondary syphilis and HIV co-infection and discusses surgical excision and fulguration as an option for definitive management.

Clinical and laboratory aspects of condylomata lata lesions of syphilis.

OBJECTIVES: Condylomata lata are a less common but distinctive syphilitic lesion. Variable theories as to their nature and origin exist. The aim of this study was to determine the clinical and laboratory characteristics of condylomata lata by determining (1): the most closely aligned stage of syphilis, based on the rapid plasma reagin (RPR) titre; (2) symptom duration and (3) Treponema pallidum PCR cycle threshold (CT) values, as an indicator of organism load. METHODS: This was a retrospective study of patients with T. pallidum PCR-positive condylomata lata lesions, attending a clinic in Melbourne, Australia, between 2011 and 2021. Syphilis serology was undertaken and RPR titres compared between condylomata lata, primary and secondary syphilis cases. RESULTS: 51 cases with T. pallidum PCR-positive condylomata lata were included. 41 cases were in men, 40 of whom were men who have sex with men (MSM), and 10 in women. Twelve of 51 (24%) cases were in HIV-positive MSM. Thirty-three of 51 (65%) had other mucocutaneous signs of secondary syphilis; 18 (35%) had no other signs of secondary syphilis. The median RPR titre among the 51 condylomata lata cases was 1:128, compared with the median RPR titre of primary syphilis (1:4) and of secondary syphilis (1:128). The median duration of lesions was 24 (IQR 10-60) days, with no significant difference between those with and without other signs of secondary syphilis (p=0.75). Median CT values for condylomata lata (CT=31) and primary syphilis (CT=31) were significantly lower than for other secondary syphilis lesion types (CT=33), indicating higher T. pallidum loads for condylomata lata and primary lesions compared with other secondary syphilis lesion types. DISCUSSION: These findings support condylomata lata as lesions that occur during the secondary stage of syphilis and which are likely to be highly infectious.
