Sexually transmitted disease caused by a bacterium called Haemophilus ducreyi.
Contagion is favored if the person has a lesion on the skin or chafing. It is more frequent in uncircumcised men and/or men with poor personal hygiene.
It manifests as one or more ulcers on the genital organs, which may be accompanied by a painful lump on the groin. Occasionally this lump may discharge pus.
Diagnosis is clinical by interrogation and genital examination.
Antibiotic treatment should be started early to control the symptoms; for example with unidose treatments of azithromycin or ceftriaxone. If a lot of pus accumulates, a small intervention may be necessary to drain it.
