Syphilitic Gumma: A Rare Form of Cutaneous Tertiary Syphilis

Syphilitic gumma presenting as squamous cell carcinoma of Vulva: A case report

Introduction

Tertiary syphilis, a late form of the disease with neurologic, cutaneous, and cardiovascular manifestations, is rarely seen in the United States in modern times. Also called the "great imitator," syphilis tends to mimic other disease processes, which can lead to a delay in proper diagnosis and treatment.

Case

We present the case of a 59-year-old woman who presented for evaluation of possible squamous cell carcinoma of the vulva. After multiple inconclusive biopsies and extensive workup with multiple providers, she was instead found to have cutaneous and neurologic tertiary syphilis. A correct diagnosis was delayed in this patient due to a presentation not consistent with classical teachings and due to a lack of access to care.

Conclusion

Syphilis has characteristic signs and symptoms, but in practice, it can have an indolent presentation that may differ from traditional presentations. To our knowledge, this is the first comprehensive case report of vulvar cutaneous syphilis masquerading as squamous cell carcinoma of the vulva. This case also provides additional evidence for the necessity of comprehensive gynecologic care and sexual history-taking in the post-menopausal populations and in rural communities.

Syphilis for dermatologists: Current concepts

Dermatologists are familiar with the classic aspects of syphilis. Our objective in this update is to display novel features of sexually acquired syphilis, its pathophysiology, natural history, atypical clinical variants, skin of color, clinical pearls, and prospects. Textbook knowledge, congenital syphilis, epidemiology, and historical data are excluded.

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.

The Mucosal Manifestations of Syphilis in the Head and Neck

Objectives: Syphilis is a resurging disease which can present itself in many ways, including lesions within the head and neck mucosa. Some of these lesions may clinically mimic oral malignancies. This literature review aims to better characterize the mucosal presentations of syphilis. Methods: PubMed, EMBASE, and clinicaltrials.gov were searched for full-text, English articles published from 1950 to 2022 that reported patients with head and neck mucosal manifestations of syphilis. Articles were screened according to PRISMA guidelines. Results: One hundred forty-three manuscripts documenting 236 individual patients were included in the review. Patients with secondary syphilis accounted for 62% of patients presenting with head and neck mucosal lesions. The most common lesions found in primary and secondary syphilis were ulcerations, primarily found on the tongue, lips, and palate. While serologic studies are the gold standard for diagnosing syphilis, biopsy of these lesions have characteristic syphilitic changes. Conclusions: Syphilis' nickname of "The great imitator" remains to be true, and the head and neck mucosal manifestations of this disease can resemble commonly seen malignancies. Awareness of this disease and its lesions is prudent given the rising incidence of syphilis within the United States.

Challenges in the Diagnosis of Tertiary Syphilis: Case Report with Literature Review

Tertiary syphilis is a large diagnostic challenge. It is rarely the case that it affects the skin, bone tissue and the eyes at the same time. The presented case shows that extensive symptomatology of syphilis poses a challenge in making a proper diagnosis in patients whose history does not suspect STDs. The study aims to present the case of a young woman hospitalized with a suspected autoimmune disease, diagnosed with symptomatic late syphilis with involvement of the skin, bones and eyes.
