The ulcer on her upper lip was misdiagnosed as herpes simplex by another physician. Sexual history revealed that the patient had oral sex with a boyfriend who had a lesion on his penis and she suspected that he had been having sex with other women. The examining physician recognized the nonpainful ulcer and rash as a combination of primary and secondary (P&S) syphilis. An RPR (rapid plasma reagin) was drawn and the patient was treated immediately with IM benzathine penicillin. The RPR came back as 1:128 and the ulcer was healed within 1 week.
