What is the primary lesion in syphilis?

Chancre
Gumma
Condyloma latum
Maculopapular rash

The correct answer is: Chancre

Syphilis is a sexually transmitted infection caused by the bacteria Treponema pallidum. Primary syphilis is the first stage of the infection, which typically begins with a painless sore called a chancre. This lesion usually appears on the genitals or mouth and lasts for 3-6 weeks. Gumma, on the other hand, is a type of tissue damage caused by untreated syphilis in its late stages. It is a non-cancerous growth typically found on the skin or internal organs. Condyloma latum, also known as genital warts, is caused by a different virus and is not a primary lesion of syphilis. A maculopapular rash, characterized by flat and raised red or pink spots, can be seen in the secondary stage of syphilis, but it is not the primary lesion. Therefore, the primary lesion in syphilis is a chancre.
