Question 1

if you have a sore that looks like chancre in your pubic area, is it syphilis?

Accepted Answer

A concern: Did you come into contact with someone who has syphilis. If the chancre is painless then it could be it. Would get it checked out and tested as it is easily treated.

Question 2

what's the difference between a canker sore and a chancre (syphilis)?

Accepted Answer

Totally Different: Canker sores are called aphthous ulcers, occur exclusively in the mouth and the cause is unknown.  A chancre is an ulcer found on genitalia and in the mouth caused by the spyrochete that causes syphilis.  Canker sores are not contagious, but chancres shed live bacteria and can spread syphilis by contact.

Question 3

hi dr's,is it true that a syphilis chancre can look a bit like an ingrown hair? could a syphilis chancre found on a males penis look just like pink soreness rather than an actual sore itself? almost like a sensitive patch? thank you?

Accepted Answer

: No it does not look like an ingrowing hair. It is a superficial ulcer and is painless.

Question 4

hi there,

i dry kissed a random woman at a club and 10 days later a small pimple like sore showed up on my lip. could it be a chancre syphilis?

Accepted Answer

Not syphilis: Syphilis is rare in heterosexuals in Canada, especially in the Vancouver area; is rarely transmitted by kissing, especially dry kissing; and a chancre would not appear as a pimple-like sore. You might just have a pimple, or maybe oral herpes (cold sore). Whatever it is, you didn't catch it from the kiss.

Question 5

1. i have read that chancres are ulcers with a clean sunken base? can chancres have a white base and start off as a large lump(almost like cheek has been bitten and swollen) and get smaller with time? 2. can syphilis be passed orally without a sore?

Accepted Answer

: Generally a syphilitics' ulcer i clean and well demarcated and heals in a few days. But variations can occur depending on situations. If there is no syphilitic lesion then chances of transmission are near 0

Question 6

std expert: have what appears to be a chancre on anus. potential exposure on 10/2, got negative tests on 11/30 and 12/27 for syphilis. test name: rpr (dx) w/refl titer & confirmatory testing. am i good to rule out syphilis as the reason for the sore?

Accepted Answer

: Have means you still have  the ulcer? If so pl see your doc and get examined for an accurate diagnosis instead of relying on your own. Yes syphilis has been ruled out

Question 7

can a herpes sore or syphilis chancre appear on the lip, less than a day (~20 hours) after exposure?

i'm asking in the context of foot fetishes and toe sucking - would that be risk for syphilis or oral herpes? thanks?

Accepted Answer

No risk, no worry: No new infection can start to cause symptoms sooner than 24 hr after catching it. And that sort of exposure is risk-free for both herpes and syphilis. If you have a new oral or lip sore, it may mean you already have oral herpes and are having a recurrent outbreak.

Question 8

can secondary syphilis begin 7 days after exposure with a sore throat, if contracted orally? no chancre, fever, or rash. sore throat was first symptom, then nausea, headache, and lymph node pain. tested neg for oral chlam&gonn at 5 weeks?

Accepted Answer

: It takes longer for secondary syphilis and it is usually accompanied by a rash. Different, non STD related infections, such as mono or CMV will have to be considered, strep throat very common as well.

Question 9

could a syphilis chancre be mistaken for a wart?

Accepted Answer

No: A chancre is an ulcer with a raw base. A wart is a small lump.

Question 10

do we have syphilis chancre in anus without anal sex?

Accepted Answer

Nope: The chancre (open sore) of newly acquired syphilis occurs only at the site of sexual exposure. The large majority of anal ulcers or sores are not syphilis. Anal fissure is most common. Herpes possible, but like syphilis, only if direct sexual contact. Secondary syphilis can result in superficial ulcers (mucous patches) anywhere on the body, but don't look like chancres. See a doctor for diagnosis.
