| In addition, the spirochetes can be viewed by examining fluid from the primary chancre or secondary lesions under the microscope. |
| In those not previously exposed to M. tuberculosis, miliary tuberculosis of the skin and tuberculosis chancre have been described. |
| Secondary syphilis develops several weeks to months after the chancre appears. |
| It may be a chancre, and it may be exceedingly serious if not properly diagnosed. |
| The chancre enlarges and often breaks in the centre, leaving a shallow ulcer. |
| This chancre may look like a pimple, blister, or open sore and usually appears in the genital area. |
