It is caused by a type of bacteria called Haemophilus ducreyi. Chancroid is characterized by a small bump on the genital which becomes a painful ulcer. Men may have just one ulcer, but women often develop four or more.About half of the people who are infected with a chancroid will develop enlarged inguinal lymph nodes, the nodes located in the fold between the leg and the lower abdomen. In some cases, the nodes will break through the skin and cause draining abscesses. The swollen lymph nodes and abscesses are often called buboes. Chancroid infections can be treated with antibiotics, including azithromycin, ceftriaxone, ciprofloxacin, and erythromycin. Large lymph node swellings need to be drained, either with a needle or local surgery.
