Syphilis Resurrected: Case Series of Palmoplantar Secondary Syphilis

Introduction Syphilis is a sexually transmitted infection caused by Treponema pallidum which has protean manifestations. The cutaneous presentation of syphilis can mimic many dermatologic conditions. Materials & methods With an aim to describe palmoplantar involvement in syphilis, a retrospective study of case series was done with 11 patients having palmoplantar skin lesions in syphilis within a period of two years. Only serologically confirmed cases were included. Results The prevalence of palmoplantar involvement in syphilis was 47.85% and all of them except one patient (congenital syphilis) were secondary syphilis. A major proportion of cases (72.8%) studied had no history or presentation of genital lesions. Biett’s collar which is an indicator of palmoplantar syphilis was seen only in 45.5% of the cases. Conclusion The clinicians must be aware that palmoplantar skin lesions might be the only clinical presentation of syphilis and a high index of suspicion is needed to correctly diagnose and treat the condition in such a setting.
