Cray = D.U.lcerous sores(Haemophilus ducreyi → painful D.U.lcers)📌 Pathophysiology• Bacteria invade at microabrasions, cause local tissue destruction → ulcers• Body responds with inflammation; pus in ulcers is infectious• Ulcers increase risk of HIV transmission!📌 Clinical Features• Painful soft genital ulcers with ragged/undermined edges• Swollen, tender inguinal lymph nodes (buboes)• Ulcer base may appear necrotic, covered in grey/yellow exudate• May merge into larger ulcers, sometimes with fever/malaise📌 Differential Diagnosis• Syphilis (typically painless ulcer)• Genital herpes (painful blisters/ulcers)• Lymphogranuloma venereum (LGV)• PCR testing from ulcer is essential for confirmation• Test for other STIs (syphilis, HIV, herpes) as coinfection is common📌 Epidemiology• Rare in the UK—more common in Africa, Asia, Latin America, Caribbean• Associated with limited sexual health resources📌 Investigations• Clinical assessment + PCR from ulcer swab (most reliable)• Culture possible but technically challenging• Always screen for other STIs!📌 Management• Antibiotics: – Single-dose azithromycin (oral) – Single-dose ceftriaxone (IM injection) – Alternatives: erythromycin or ciprofloxacin• Supportive care: pain relief, saline compresses• Incision/drainage for fluctuant lymph nodes (buboes) if needed• Public health: Contact tracing & partner treatment—vital to stop reinfection📌 Complications• Abscess formation (from untreated buboes)• Secondary infection, scarring/disfigurement• Greatly increased HIV transmission risk if untreated📌 Prognosis• Excellent with prompt antibiotics—ulcers usually heal without much scarring• Delayed treatment → abscess, scarring, public health risk📎 More MSRA Chancroid Resources:📝 Revision Notes: https://www.passthemsra.com/topic/chancroid-revision-notes/🧠 Flashcards: https://www.passthemsra.com/topic/chancroid-flashcards/💬 Accordion Q&A: https://www.passthemsra.com/topic/chancroid-accordion-qa-notes/🚀 Rapid Quiz: https://www.passthemsra.com/topic/chancroid-rapid-quiz/🔗 Quiz: https://www.passthemsra.com/quizzes/chancroid/🎓 Infectious Diseases for the MSRA: https://www.passthemsra.com/courses/infectious-diseases-for-the-msra/#MSRA #Chancroid #STI #GenitalUlcer #MSRARevision #InfectiousDiseases #ExamPrep #GPTraining #Antibiotics #SexualHealth #PassTheMSRA #RevisionPodcast
