Overview
Lymphogranuloma venereum (LGV) is an uncommon sexually transmitted disease caused by certain types of the bacteria called Chlamydia trachomatis. It is spread through having unprotected vaginal, oral, or anal sex. Lymphogranuloma venereum causes painful and swollen lymph nodes, which can then break down into large ulcers. The disease goes through 3 distinct stages as it develops. The first 2 stages of lymphogranuloma venereum may be minor, and you might not even be aware of any symptoms until you reach stage 3, called the genitoanorectal syndrome.
