Increasing incidence of syphilis: A case report of non-resolving papulosquamous rash and role of a biopsy in the prevention of delayed diagnosis

Le résumé fourni par la source

Syphilis is a sexually transmitted infection that is undergoing a resurgence in Canada and around the world. If not diagnosed correctly, syphilis can progress to its secondary and tertiary stages, affecting numerous organ systems. We present a case of a 41-year-old female who developed a papulosquamous rash, initially diagnosed as varicella with progression to a widespread and painful rash over 3 months. Based on clinical, histological, and serological findings, she was later diagnosed with secondary syphilis and successfully treated with intramuscular penicillin. This case underscores the importance of accurate diagnosis and treatment of syphilis to prevent systemic complications. We advocate for increased awareness among frontline providers with a proactive approach to diagnosis and management, including thorough history and physical examination, low threshold for performing serological testing, biopsy for lesions that do not resolve as expected with management, and multidisciplinary involvement for complex presentations of syphilis.
