If you do, syphilis may fool you the next time you see a patient with a nondescript rash.<\/p>\n<p>Why are we bothering with syphilis anyway, when we are faced with more pressing problems like diabetes, cardiovascular disease, HIV, cancer, and\u00a0 Alzheimer\u2019s? Well, syphilis may not be as frequent as those conditions but it remains a common, and commonly-missed, disease. Part of the problem is that it can manifest itself in so many ways and mask itself in the guise of common problems like contact dermatitis, muscle tension headaches, osteoarthritis, URIs, alopecia, etc. It did not earn itself the moniker \u201cThe Great Imitator\u201d for no good reason.<\/p>\n<p>I do not intend this post to be an exhaustive treatise on the diagnosis and treatment of syphilis. The best place to find such information is in a textbook or UpToDate. But I do want to mention a few key points to keep in the back of our minds as we see patients:<\/p>\n<ul>\n<li>The most common manifestation of primary syphilis is a painless papule appearing at the site of inoculation, which usually turns into a small ulcer or chancre.<\/li>\n<li>Frequently, a person will manifest symptoms from secondary syphilis despite never having seen a chancre. The wide variety of symptoms of secondary syphilis is what can throw astute clinicians off track.<\/li>\n<li>One of the more common symptoms of secondary syphilis is a maculopapular rash, often on the torso, similar to the dime-a-dozen rashes we all encounter every day. See below for a picture. Anytime you see a patient with a maculopapular rash, include the possibility of syphilis in your differential. Serologic testing is simple.<\/li>\n<\/ul>\n<p>\u00a0<img data-opt-id=128510896  fetchpriority=\"high\" decoding=\"async\" alt=\"Image\" src=\"http:\/\/www.uptodate.com\/contents\/images\/ID\/79451\/Trunk_rash_secondary_syphil.jpg?title=Trunk+rash+secondary+syphilis\" \/><\/p>\n<ul>\n<li>The diagnosis of syphilis rests on darkfield microscopy of a chancre (primary syphilis) or serologic testing (for later stages).<\/li>\n<li>Syphilis should always be reported on a confidential morbidity form to your county public health department. Your county officials will do their best to track down all possible contacts of the index case and enlist their cooperation. (On a related note, no matter how bad your day in clinic gets, think of what kind of day your poor, hard-working county public health official\u00a0is having\u00a0trying to track down syphilis exposures. No wonder syphilis has been around for over 500 years with little hope in sight for eradication.)<\/li>\n<\/ul>\n<p>OK, in closing, let me mention a few other terms people use in referring to syphilis. A common clinical term is lues. On the street it can be referred to as bad blood, syph, or the clap. In 1494, it was called \u201cFrench Disease\u201d by soldiers from Naples when the French and the Neopolitans were at war with each other. The French, not surprisingly, called it \u201cNeopolitan Disease.\u201d In the interests of tact and diplomacy, we will avoid taking sides in this ongoing controversy.<\/p>\n<p>Richard Fleming, MD<\/p>\n","protected":false},"excerpt":{"rendered":"<p>If an august, gray-haired professor delivered your medical school lecture on syphilis, or if you had to suffer the pontifications of a wise-acre resident on the I.D. service during internship, you may recall that syphilis was formerly known as \u201cThe &hellip; <a href=\"https:\/\/phcprimarycare.org\/?p=169\">Continue reading <span class=\"meta-nav\">&rarr;<\/span><\/a><\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"jetpack_post_was_ever_published":false,"_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_jetpack_memberships_contains_paid_content":false,"footnotes":""},"categories":[1],"tags":[],"class_list":["post-169","post","type-post","status-publish","format-standard","hentry","category-uncategorized"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.5 -
