A Peculiar Presentation of Syphilis as a Mysterious Rash: A Dermatological Dilemma.

A renowned poet in the ancient city of Verona by the name of Girolamo Fracastoro coined the term syphilis in 1530. The stigma and shame that embodied this affliction has been time immemorial and disabling for patients. The hypothesis of the spread from the warm tropics of west and central Africa to the Iberian Peninsula accompanied by the slave trade has been a tale for centuries. Malignant syphilis is a rare skin manifestation of Treponema pallidum infection and a variant of secondary syphilis. The rash is frequently associated with HIV-infected patients, often with low cluster differentiation 4 (CD4) cell count. The authors reported a unique case involving a 46-year-old woman who presented with a one-week history of skin eruptions at various stages. Subsequent laboratory tests revealed a strong positive result for Treponema pallidum and a positive Rapid Plasma Reagin (RPR) test with a titer of 1:16. She received doxycycline because she had a history of penicillin anaphylaxis in the past. She did well, with a remarkable improvement in symptoms - a positive outcome for this catastrophic stigmatizing, rare diagnosis.
