    The secondary syphilis. A couple of things that you very much want to keep in mind with secondary syphilissyphilis that you will not find with primary. First, it’s five weeks after primary lesion. Go in odd numbers. We have three and five. Three weeks after the lesion will be primary. Five weeks after the primary would be secondary. What are you going to find in secondary? Proliferation of spirochete and the skin and the mucous membrane become involved. Skin is huge. And the reason I say skin is in the picture. You’ll find these lesions on the palms and the soles. Secondary syphilis. You will not find this is in primary. Most likely. Moist areas are also where you would find these lesions. You’re thinking about the axilla or anogenital region, and then the mucous membranes include your mouth, the throat, the vagina. All part of your syphilitic secondary type. Primary and secondary, keep them separate. The tertiary would be five years or more after initial infection. So now, the number that you want to know for sure or your area code is 3-5-5. Three weeks for primary. Five weeks after the primary for secondary. Five years after, you then develop tertiary. This is the one that you have probably seen many times in -- Well, we’ve talked about this in cardiology and you’ve also talked about this in neuroscience, with something called tabes dorsalis. When did we talk about this in cardiology? I gave you that murmur in which you’d find the murmurby the third intercostal space, left peristernal. What is that? Remember, please, if the blood vessels are being involved and they’re obliterated, we call this what in tertiary syphilis? Endarteritis obliterans. If you knock out the endarteries of the big aorta, the aorta dies or it becomes...
