Does a chancre on genitals always mean than an STI is present?

In brief: The chancre

Has a hard edge, usually dry and painless.
Caused by treponema palidum, sphylis. A chancroid is the same size, painful, oozes, soft edge. Caused by haemophilis ducreyei. Both are sti's. So yes, but not all are syphilis. The chancre goes away, but the disease persists.
