Does keratolysis exfoliativa can misdiagnosis with syphilis rash ?

Rules of the road: One of the rules in medicine is that a rash related to syphilis infection can appear in a great variety of ways and be confused with other types of rashes. That means any patient who is at risk for having syphilis should get checked or rechecked for syphilis by doing blood tests. If there is for sure no syphilis, that solves the rash confusion problem.
