genital ulcer.pptx
1. Genital ulcer diseases other
than syphilis
Presenter : Dr. Sasmita Mishra
Moderator : Dr. Biswanath Behera
2. Chancroid
• Causative organism-Haemophilus ducreyi, fastidious gram negative coccobacillus
• Incidence- High risk
a) Lower socioeconomic status
b) Commercial sex workers
c) Uncircumcised men
Male to female ratio- 3:1-53:1
Prevalance- 0.0%-0.15%
3. Pathogenesis
Inoculation through minor trauma/ abrasion
IL-8 IL-6
Stimulate PMNs and stimulates CD4- Tcells
macrophages
Pustules ulceration by IL-2 activation
• Cytolethal Distending Toxin (CDT)- Virulence factor for ulceration
4. Clinical features
• Incubation period- 1-14 days (avg 7 days)
• Evolution of lesion-
Erythematous papule pustule ulcer
2-3 days 2-3 weeks (soft chancre)
• Characteristics of ulcer-
Single/Multiple, painful, non-indurated
undermined ragged edge
necrotic yellowish-gray exudate
Base with granulation tissue
5. Contd……….
• Onset- 1 -2 weeks , seen in- 50-60% cases, usually unilateral
• Lymph nodes –Painful, enlarged, tender, matted- Bubo
• If untreated, unilocular abscess sinus
• No systemic infection
• Asymptomatic carrier rare
• Females may have painless ulcer
6. Sites
• Genital:
Male- prepuce,frenulum, coronal sulcus
Female- Fourchette, vestibule, labia, clitoris, vagina
• Extragenital:
Breast, fingers, thigh, oral cavity, lip
Rarely involved due to autoinoculation
• Perianal ulcers- usually seen in men who have sex with men (MSM)
9. Diagnosis
• Usually clinically
• Gram’/Wright’s stain- School of fish appearance.
• Ito- Reenstierna test (intradermal test) - Obsolate now
• Definitive diagnosis- Culture ( Chocolate agar)
PCR (most sensitive)
10. Histopathology
• Shows 3 distinctive zones
a) Top zone- narrow, consisting of neutrophils,fibrin
erythrocytes, necrotic tissue
b) Middle zone- wide, newly formed blood vessels
with marked endothelial cell proliferation
c) Lower zone- dense infiltrate of plasma cells &
lymphoid cells
12. Criteria for probable diagnosis according to CDC
• 1 or more painful genital ulcers
• Dark field examination of exudate- negative for T. Pallidum
• Non reactive serological tests - at least 7 days after onset of ulcers
• Typical clinical finding with regional lymphadenopathy
• Negative test for HSV (HSV PCR / Culture)
13. Management ( According to CDC)
• Azithromycin 1g orally as single dose, or
• Ceftriaxone 250mg IM as single dose, or
• Ciprofloxacin 500mg BD for 3 days, or
• Erythromycin 500mg TDS for 7 days
14. Drug resistance
• Plasmid mediated
• Integrated Conjugative resistance Element (ICE)- also responsible
• Resistance develop to ampicillin, chloramphenicol, tetracycline
15. Management of bubo
• Adequate antibiotic coverage with aspiration
• If size < 5 cm- heals with resolution of genital ulcer
• If size > 5 cm- not correspond to resolution of ulcer
• Advantage of Incision and drainage- Effective, safe method, avoids frequent
needle re-aspiration, early healing of lesion
16. Post- treatment follow up
• At 3rd day and 7th day of initiation of treatment
Symptomatic Significant
improvement re-epitheliazation
• If no response to treatment- coinfection with T. Pallidum/HSV suspected
• Sexual partner treated : < 10 days
• HIV and VDRL – to repeat after 3 months
17. Donovanosis
• Caused by- Klebsiella granulomatis, Gram negative intracellular bacteria
• Epidemiology- Risk factors includes
a) Low socioeconomic status
b) Overcrowding
c) Poor hygiene
• M:F- 4:1
• Prevalance- 6.3%
• Age group -20-40 yrs
18. Contd………
• Route of transmission- Trauma/abrasion during sexual contact
Autoinoculation
• Sites- Most common- Genitals ( Coronal sulcus, prepuce, glans penis in male,
labia minora, fourchette in female)
Others- Inguinal region, anal area, oral cavity
urethra and rectum spared
19. Clinical features
• Incubation period- 40-50 days
• Evolution- Single/Multiple firm papules
Granulomatous ulcer
• Ulcer characteristics-
Slowly progressive,painless
Beefy red in colour
Bleeds on touch
• Subcutaneous extension - Pseudobubo
20. Morphological variants
Classical granulomatous type-
• Most common presentation
• Edge thin and undermined
• Granulation tissue overflow from the edge
• Skin around ulcer slightly edematous and infiltrated
• Non capsulated organism found
21. Contd……..
Hypertrophic type-
• Ulcer edge thickened and raised above surrounding skin
• Consists of pale red, course ,warty granulation tissue ( Buckled appearance)
• No exudates
• Capsulated organism found
22. Contd……..
Sclerotic/Cicatrical :
• Early and extensive formation of fibrous tissue
• Results in deformities of genitalia
Phagedenic (Destructive/Necrotic type) :
• Due to superadded anaerobic infection Ulcer becomes painful
25. Diagnosis
• Direct microscopy- Donovan bodies- Mononuclear cells with organism
( safety pin appearance)
Gold standard
• Biopsy- indicated in chronic ulcer
• Serological tests- Complement Fixation Test
• Culture
• Colorimetric detection system

STDs Effects
Chancroid Large ulcer, longer persistence, multiple inguinal
buboes, frequent occurrence of giant and phagedenic
ulcer
Herpes genitalis Deep progressive ulcers, haemorrhagic and ecthyma
like lesions, hyperkeratotic verrucous
lesions,pseudotumour of tongue
Granuloma inguinale Larger,extensive lesion, pseudobubo may burst
producing ulceration, slow response to treatment
LGV Acute inflammation, bilateral inguinal bubo may burst
into ulceration.
54. Prevention
