Derm: Pompholyx: Free MSRA Podcast

✅ MSRA Deep Dive: Pompholyx – Vesicles, Triggers, and ManagementIn this focused MSRA revision episode, we explore Pompholyx (also called dyshidrotic eczema), a distinct form of eczema that causes intensely itchy vesicles on the hands and feet. If you're revising dermatology, this one is high-yield. We break down everything from presentation and differentials to treatment and prognosis, following UK NICE-aligned content.🧠 Key Learning Points📌 Definition• Pompholyx is a vesicular eczema primarily affecting palms, fingers, and soles• Also known as dyshidrotic eczema, but not due to sweat gland blockage• Name comes from Greek “pompholix” meaning “bubble”📌 Pathophysiology• Caused by inflammatory skin changes, not sweat retention• Thought to involve skin barrier dysfunction, immune dysregulation, and environmental triggers📌 Triggers• Stress, heat, humidity, excessive handwashing, contact allergens, and irritants• More common in people with atopic background (eczema, asthma, hay fever)🔍 Clinical Features• Sudden onset of small fluid-filled blisters (1–2mm vesicles) on sides of fingers, palms, or soles• Severe itching or burning• Lesions may burst, peel, or crust, leaving behind dry, cracked skin• Flares typically last 3–4 weeks• Nail changes (transverse ridges or pits) if inflammation involves nail matrix🧠 Differential Diagnoses• Pustular psoriasis (palmar/plantar)• Tinea infections• Contact dermatitis (allergic or irritant)• Bullous impetigo, bullous pemphigoid, linear IgA disease• Juvenile plantar dermatosis, erythema multiforme, herpes simplex, and fixed drug eruptions📌 Key point: Always consider testing or referral if the clinical picture is unclear or resistant to treatment🧪 Diagnosis• Clinical diagnosis in most cases• Investigations if atypical or recurrent:• Bacterial swabs (if secondary infection suspected)• Fungal scrapings or biopsy (to rule out tinea)• Patch testing (for contact allergens)• Bloods/HTLV1 only if suspecting rare T-cell lymphoma variant💊 Management🎯 First-line• Emollients – restore skin barrier• Topical corticosteroids – reduce inflammation• Cold compresses, antihistamines (for itching)• Avoidance of triggers (soaps, irritants, allergens)🎯 Second-line• Oral steroids (e.g. prednisolone) for short-term flare control• Topical calcineurin inhibitors (tacrolimus/pimecrolimus)• Phototherapy (UV light) for resistant cases🎯 Severe/Refractory Cases• Immunosuppressants: methotrexate, azathioprine, mycophenolate, cyclosporin• Botulinum toxin (may help reduce sweat triggers)• Allotretinoin (retinoid under specialist care)• Drainage of tense bullae if painful• Antibiotics if secondary infection develops📈 Prognosis• Usually chronic and relapsing• Flares resolve in 3–4 weeks, but recurrences are common• Quality of life often affected due to pain, itch, and disrupted sleep/work• Secondary infection, lichenification, and post-inflammatory pigmentation may occur• Prognosis generally good with trigger control and consistent treatment🩺 MSRA Exam TipIf you see itchy vesicles on hands/feet, think Pompholyx.Don’t forget the misnomer: not caused by sweat ducts.Differentiate from tinea, psoriasis, and contact dermatitis.📚 MSRA Revision Resources📝 Notes: https://www.passthemsra.com/topic/pompholyx-revision-notes/💬 Flashcards: https://www.passthemsra.com/topic/pompholyx-flashcards/🧠 Accordion Q&A: https://www.passthemsra.com/topic/pompholyx-accordion-qa-notes/🧪 Rapid Quiz: https://www.passthemsra.com/topic/pompholyx-rapid-quiz/🎯 Full Quiz: https://www.passthemsra.com/quizzes/pompholyx/📘 Dermatology Course: https://www.passthemsra.com/courses/dermatology-for-the-msra/🏷️ Hashtags#MSRA #MSRARevision #Pompholyx #DyshidroticEczema #MSRAPodcast #MSRAFlashcards #MSRAQuiz #PassTheMSRA #FreeMSRA #Dermatology
