Abstract

Background: Syphilis is a sexually transmitted infection with increasing incidence in the United States. Presentations of syphilis vary widely and can be easily mistaken for other diagnoses, including cancer, especially in atypical cases. Case description: At her delivery after no prenatal care, a 35-year-old woman was found to have exophytic vulvar and perianal lesions, inguinal lymphadenopathy, and a new diagnosis of HIV, with a strong clinical concern for vulvar and/or anal carcinoma. She was subsequently diagnosed with presumed late latent syphilis and began weekly intramuscular penicillin G benzathine treatment. CT imaging demonstrated a perineal plaque-like area with bilateral inguinal, external iliac and retroperitoneal lymphadenopathy. She was seen in gynecologic oncology clinic one week after her initial presentation with notable improvement in the vulvar lesions, raising suspicion for condyloma lata rather than invasive or preinvasive disease on the vulva, however concern remained for dysplasia in the perianal lesion. Another week later, she underwent an exam under anesthesia with vulvar and perianal biopsies revealing chronic inflammation and granulomatous change without evidence of malignancy or dysplasia. At the four week post operative visit, there was almost complete resolution of the lesions. Conclusion: Syphilis should be considered in the differential diagnosis of atypical vulvar lesions.
