Derm: Molluscum contagiosum: Free MSRA Podcast

🧑‍⚕️ FREE MSRA PODCAST – Molluscum Contagiosum: Recognise, Reassure, Refer🎯 Your rapid revision session for one of dermatology’s most common viral infections. We cover diagnosis, management, red flag scenarios and the must-know referral pathways for the MSRA.Key Learning Points🔍 Definition• Molluscum contagiosum is a common, self-limiting viral skin infection caused by the molluscum contagiosum virus (MCV, poxvirus family).🦠 Transmission & Risk Groups• Spread by direct skin contact or sharing contaminated objects (towels, clothing, toys).• Most common in young children, but also seen in immunocompromised patients and sexually active adults (anogenital lesions).• Key risk groups: children with eczema, people with HIV or immunosuppression.💡 Pathophysiology & Clinical Features• Classic appearance: small, firm, dome-shaped, flesh-coloured or pearly papules with a central umbilication (dimple).• Painless, often multiple, sometimes itchy or inflamed.• Distribution: flexures, trunk, face in children; genital area, pubis, thighs in adults (if sexually transmitted).• Incubation period: 2–8 weeks. Infectious while visible lesions remain.📈 Epidemiology• Very common (esp. children 1–10 years).• Peaks: young children and sexually active young adults.• Immunosuppressed patients can have extensive/atypical lesions.🧠 Mnemonic for Referral Red Flags:H-E-A-RHIV or known immunosuppression (extensive, persistent lesions → urgent referral)Eye involvement (eyelid lesions with red eye → urgent ophthalmology)Adult anogenital lesions (GUM referral for STI screening)Recalcitrant or rapidly spreading cases (consider immune status, refer if severe)🩺 Diagnosis• Nearly always clinical—look for the classic umbilicated papules.• Dermatoscopy can help confirm, but histology/PCR rarely needed.• Always consider HIV or immune workup for persistent, widespread or atypical cases.💊 Management• First line: Reassurance—self-limiting (resolves within 6–18 months).• Advise: avoid scratching, don’t share towels, moisturise, don’t exclude from school/swimming.• Treatment (if distressing, inflamed, or for transmission): options include curettage, cryotherapy, topical agents (imiquimod, cantharidin—limited evidence, risk of irritation/scarring).• Treat associated eczema with mild topical steroids.• Antibiotics only for secondary bacterial infection.⚠️ Complications• Secondary infection (impetigo, cellulitis), scarring (from scratching or treatment), persistent/multiple lesions in immunocompromised, eye involvement (conjunctivitis), psychosocial distress.📎 More MSRA Revision for Molluscum Contagiosum:📝 Revision Notes: https://www.passthemsra.com/topic/molluscum-contagiosum-revision-notes/💬 Flashcards: https://www.passthemsra.com/topic/molluscum-contagiosum-flashcards/🧠 Accordion Q&A: https://www.passthemsra.com/topic/molluscum-contagiosum-accordion-qa-notes/🚀 Rapid Quiz: https://www.passthemsra.com/topic/molluscum-contagiosum-rapid-quiz/🧪 Full Quiz: https://www.passthemsra.com/quizzes/molluscum-contagiosum/🎓 Dermatology Course: https://www.passthemsra.com/courses/dermatology-for-the-msra/🌐 For more free & premium revision resources:https://www.passthemsra.com#MSRA #MolluscumContagiosum #DermatologyMSRA #MSRARevision #MSRAFlashcards #PassTheMSRA #FreeMSRA #ViralSkinInfection #Poxvirus #RedFlagReferral
