Chancroid is sexually transmitted infection characterized by painful sores on the genitals and large lymph nodes in the groin.[3][4] The ulcers are generally 1 to 2 cm in size.[4] The lymph nodes may grow to such a size that they rupture.[4] Onset is 4 to 10 days after exposure.[4]
It occurs due to the bacteria Haemophilus ducreyi.[3] It spreads between people by sex, with the risk being 35% during an episode of contact.[4] In spreads more readily in those who are uncircumcised.[4] Diagnosis is often based on symptoms, though may be confirmed using a special culture media or PCR.[4]
Treatment is with antibiotics such as azithromycin or ceftriaxone.[4] With treatment symptoms should improve within 2 weeks.[4] Fluid filled lymph nodes may required incision and drainage.[4] Sexual partners should also be treated.[4] Without treatment, the ulcers generally heal within 1 to 3 months.[4]
Chancroid is rare.[4] In the United States less than 20 cases are diagnosed a year.[3] Those between 20 and 30 are most commonly affected.[4] It occurs more frequently among sex workers.[4] While a disease with compatible symptoms has been described since the time of the Ancient Greeks, chancroid was first differentiated from syphilis in the mid-1800s.[5]
