Chancroid is an acute sexually transmitted disease characterized by a painful genital ulcer and painful lymph node swelling. It is caused by the bacteria Haemophilus ducreyi. Incubation is typically 4 to 7 days. Symptoms include tender genital ulcers with well-defined borders and a gray or yellow discharge. Untreated, ulcers can enlarge and buboes may form abscesses. Diagnosis is by gram stain or culture of the ulcer. Treatment is with antibiotics like azithromycin or ceftriaxone. Left untreated, complications can include large draining ulcers or abscesses.

erosion and ulcer.

7. Skin lesions :
 Ulcers may be single or multiple or merge to
form large ulcers.
 Suppurative Lymphadenopathy ,painful,
(usually unilateral) occur within 1 to 2 weeks
of the lesion.
 Buboes may drain spontaneously.

8. Investigations :
 Gram stain: Scrapings from base of ulcer may
show clusters of gram negative rods
(SCHOOL OF FISH).
 Culture : Difficult, special media, Sensitivity
< 80%.
 Serologic tests : None, Should be tested for
syphilis and HIV. Repeat after 3 months if –
ve initially.

9. Management :
 Azithromycin : 1 gm Single dose.
 Inj. Ceftriaxone : 250 mg IM single dose.
 Ciprofloxacin : 500mg bid for 3 days.
 Reexamination after 3 to 7 days.
 Buboes may need to be aspirated.

10. Complications :
 Large inguinal abscess may develop & rupture to form
draining sinus or giant ulcer
 Superinfection by Fusarium & Bacteroides
 Phimosis- in long standing lesions
