I am not sure if my second question went through. are primary syphilis chancres always like the pictures online.. open sore, ulcerated or can they take a different appearance? like crusted flat spot on skin?
I looked them up.. all seem to be open sore, or ulcer. but then I read where they can take on just about any appearance it makes me wonder,. would a primary chancre look like rough patch of skin?
Google has some very good pictures of syphilis sores, take a look.
