What is the tertiary lesion in syphilis?

  1. Chancre

  2. Condyloma latum

  3. Gumma

  4. Maculopapular rash

The correct answer is: Gumma

In syphilis, the tertiary lesion is known as a gumma. Tertiary syphilis typically develops years after the initial infection if left untreated. A gumma is a non-cancerous growth or soft, non-tender swelling that can occur in various organs of the body, including the skin, bones, liver, and other tissues. It is characterized by a central necrosis surrounded by inflammation. It is important for dental professionals to recognize this lesion as it can manifest in the oral cavity, leading to destructive consequences if not properly managed. Chancre is the primary lesion of syphilis, which appears at the site of initial infection. Condyloma latum is a manifestation of secondary syphilis and presents as flat, wart-like growths in moist areas of the body. Maculopapular rash is also a characteristic feature of secondary syphilis, appearing as a rash on the palms and soles of the feet.
